1. Introduction

Taking into account the Government of Luxembourg's policy to reform the civil services and to promote an easier access of State's Services especially through the internet, the National Cadastre and Topography Administration (ACT) contributes to the national eLuxembourg program and offers a new internet service to the public services as well as to the citizen in general.

With the National Geoportal of Luxembourg, ACT has created a powerful tool to communicate with the users. This tool is designed to provide the cadastral and topographic information and data which are under the responsibility of ACT, as well as geodata from other providers cooperating with the system.

The main targets of the geoportal are:

  • Easier access to the data of ACT and the other connected providers
  • Faster delivery of ordered products and data
  • Reduce the staff workload by eliminating tasks which can be done automatically
  • More transparent interaction between Civil Service and customer
  • Create a central geodata exchange platform for Luxembourg
  • Provide a key element of the national geodata infrastructure of Luxembourg
  • Contribute to satisfy the national and international needs for geodata and metadata

2. General information

2.1 Scope

This document is targeted at the general public using the geoportal, i.e. all the non identified users who access the geoportal to view maps and product informations. The according functions are explained in the following chapters.

2.2 Conditions for using the geoportal

Please consider the following when using the geoportal:

  • In general the latest versions of the following internet navigators and OS are supported :
    • MOZILLA (MAC OS, WINDOWS, LINUX)
    • FIREFOX (MAC OS, WINDOWS, LINUX)
    • EXPLORER (WINDOWS)
    • SAFARI (MAC OS)
  • Internet access via: http://www.geoportal.lu
  • Several functions are reserved to authenticated users : the eShop, the OGC compliant webservices and the providers' functions can only be accessed with a user account and corresponding password

2.3 General architecture of the geoportail

The following picture illustrates the overall architecture of the geoportal, with the general user entering via a standard internet browser.

The system consists of different parts, whereof the Portal is the central element.
For all types of users, the Portal is the access point for the different functions.
They can use the mapping tool to vizualize maps and other geodata or get general information or details about the different products that can be ordered via the system. If they have an own user account they can send orders.
Next to the Portal is the section of the “geodata and product providers” of the geoportal. They handle the incoming orders and provide the data and information in the portal. The Portal has a series of specialized functions for these purposes.

2.4 General view of the geoportal

The geoportal home page actually looks like this:

The general public user can always access the information section and use the functions in the sections “Maps and Products” and “Ask a question”.

All the functions of the mapping tool are explained in this manual.

The button “Our Products” opens the catalogue of the products available in the geoportal. This is a catalogue containing all the existing products offered by the different providers. The information sets about the products contained in the catalogue are called “metadata sets”.

In the section “Ask a question”, the menu “FAQ” ( Frequently Asked Questions) contains a list of questions + answers that may be of interest for many users. Any one can read the questions and answers.

With the button “Ask a question”, the user can formulate questions himself, which will be answered by the geoportal support team.

An authenticated user (login, password) can access to other functions that are adapted following his personal rights and permissions in the system.

In every case, he can use functions to

  • send orders of the products available to him,
  • manage his orders in the menu “manage my orders”, and
  • view his orders in the order archive under “archive”.

In this case, he has the status “customer” in the geoportal.

If he has other further going rights in the system, like

  • the right to use the OGC web services to integrate geodata in his local GIS system,
  • the right to view and use special geodata not available to the general public,
  • the right to create and manage his own subordinate accounts,

he becomes “special customer” of the geoportal.

If the user is a geodata and product provider of the geoportal, he has access to the special functions reserved for the providers:

As a geodata and product provider, the user is enabled to :

  • Handle the orders: directly in the Portal, he can handle incoming orders by changing the order status, type informations and prices, and upload files to be retrieved by the customers.
  • Manage the products: in the Portal the provider creates the products he wants to offer, or whose existence he wants to publish.
  • Create metadata: the provider has to create and update the metadata about his products, i.e. the information about the products' whereabouts contained in the product catalogue.
  • find old orders in the geoportal “Archive”.
Note : The contents of this manual can in no case imply obligations of service delivery or guarantee from ACT or other geoportal providers!

3. Ergonomics

In this chapter the general way to use the geoportal's functions is described.

3.1 Page structure

All the pages are composed of:

  • A header : the horizontal stripe and one or more lines with general functions
  • A menu on the left side : the specific functions of the geoportal
  • A principal part : Static and dynamic information in connection with the actual function
  • A footer

3.2 Navigation principles

The navigation principles are the same on every site page.

On the 1st and 2nd level, the navigation is organized in the vertical navigation bar on the left side, with mouse-over effect and highlighting of the active link by means of color change from blue to orange.

From the 3rd level downwards, navigation is incorporated in the page contents.

Every page has an arrow button on the upper right, which leads to the superior level.

3.3 Presentation of the content pages

The pages generally display a frame with a title composed of:

  • the function of the superior level
  • the actual function

On the 1st navigation level, the pages contain a brief presentation of all the 2nd level functions.

On the 2nd navigation level, the pages contain the specific information for the actual function.

3.4 Footer

Top of the page

By clicking on the link mentioned above, the user can go back to the top of the page.

At the bottom of every page, on the right, the following information is displayed:

  • © Editor
  • Legal aspects concerning the use of the website
  • Contacts

3.5 Languages

The geoportal is multilingual : Luxembourgish, French, German and English are supported. To change the language, click on the corresponding button on the upper left of the page:

3.6 Paginated lists

All the lists with search results are paginated and contain the information split into different pages. The properties of the list contents are displayed:

  • Total number of items in the list
  • Links to the different list pages, where the actual page is displayed in bold characters
  • Arrows to open the page before, or the next page
  • A button to display the complete list without pagination

3.7 Sort

All the lists can be sorted by any of its columns, either in ascending or descending way.

After being sorted, the list is reinitialized and the first list page is displayed.

3.8 Tags

To clearly present the contents, tags are frequently used.

Every tag header reacts to clicking. When a new tag is opened, the fields in the actual tag are automatically validated before switching to the new tag.

3.9 Actions

FIXME

The different actions that can be done at a certain stage are represented by hypertext links, whose clickable text explains the action.

The different options are simply separated by the character .

Except for the very specific actions, the current actions will generally use the following terms:

  • Create : to create a new entity
  • Modify : to modify an existing entity
  • Validate : to validate and store encoded values
  • Cancel : to disregard the newly encoded values and restore the original values in the fields
  • Back : to go back to the element before or to the upper level

The text is completed by an indication of the entity on which the function operates. For example “Back to the order list”.

3.10 Colours

A simple colour code is used in the interface, to specify the current state:

  • Blue : validated and inactive part
  • Orange : activated part currently undergoing modification

Note : For tags without any content, the text remains blue and italic, and will not be reactive to clicking.

3.11 Procedures with multiple steps

For complicated procedures with an important number of intermediary actions, the user is guided through different steps like shown in the example.

The steps already passed and validated are indicated in normal font, the current step in bold font, and the next steps in italic font.

At every moment, the user can go back one ore more steps by simply clicking on the link of the corresponding step.

3.12 Warning messages

The geoportal exchanges information with its user. This can be data or information concerning the user's actions.

3.12.1 Information message

When an action of the user does not give any visible result on the screen, the system shows a message to indicate that the action has been done with success. For examble, after sending an order, the system shows the following confirmation message:

3.12.2 Error message

In case of an error, when entering data, the system alerts the user that some rules have not been respected and specifies the problem that has to be corrected.

3.12.3 Confirmation request

The user sometimes has to proceed to actions which cannot be reversed. To evitate mistakes with heavy consequences, the system aks for explicit confirmation before proceding. This happes in form of a confirmation message to be validated by clicking on the « OK » button, or the « Cancel » button.

4. Actors, Authentification, Access, Rights and User Accounts

In the geoportal exist several user levels. Every user has a user account associated to a set of profiles. In the profiles the individual rights concerning the mapper, the catalogue the webservices and the overall geoportal functions are saved.

The following chapter explains the principles that rule the geoportal and that make sure that the access restrictions can be adapted very finely to the user’s needs.

4.1 Actors in the geoportal

The actors in the geoportal can be split into 4 groups:

The "General Public"

When opening the geoportal's home page, the user automatically acts as a “general public” user, as long as he has not logged in the system by providing his user account name and his password. The “general public” is the anonymous standard user, who is granted with the minimal user rights in the system and who can do the basic operations in the geoportal. He can learn about the existing and available products by viewing the metadata catalogue's contents, and view the geodata in the mapping tool. He is also allowed to ask questions to the geoportal's support team and to read the FAQ. He CANNOT order products.

The "Client"

Unlike the “General Public”, the “client” has an individual user account associated to a password, which allows him to authenticate himself in the system. He has access to the “order” menu and can send orders or estimate requests concerning the available products in the catalog. In the order menus, he can check the state of his different orders and eventually download ordered files. For more information, please read the corresponding chapters in the geowiki.

The "Special client"

The “Special Client” is also authenticated via his user account and his password. He has all the rights of the “client” but additionally, he can access to some specialized functions that require previous regulations. Depending on the granted rights, he can

  • Create and manage his own sub-accounts (f.ex. in the case of large firms) and allocate them part or all of his own rights in the system.
  • View other supplementary data in the geodata mapper, which are not available for the general public.
  • Be granted less strict restrictions concerning the visibility of geodata in the geodata mapper, like the possibility to combine different geodata that are blocked for the general public, view attributes or use some geodata at scale levels that are not allowed to the general public.
  • See and order specialized products that are not available to the general public.
  • Use the WMS (Web Map Server) and WFS (Web Feature Server) webservices, that are compliant to the OGC (Open Geospatial Consortium) specifications and offered by that the geoportal's providers.

The "Provider"

The “provider” is the highest-ranking actor in the geoportal, thus the one with the maximum level of rights and functions. He generally has all the rights of a “special client” but has some additional rights / functions to

  • Publish his own geodata layers in the geodata mapper. This happens by the means of OGC compliant webservices, which are integrated in the mapping tool after validation by the geoportal's administrators.
  • Offer his own geoproducts.
  • Retrieve and handle the incoming orders and estimate requests of the clients in the portal (manually or automatically).

4.2 Root Accounts & Subordinate Accounts

Subordinate accounts are used to delegate the management of the individual user accounts of customer organizations to one single main (« root ») account, without any interaction by the geoportal’s management. This means great flexibility for the customers as well as an easier task for the geoportal management team.

The owner of a root account can open new individual user accounts. Every single subordinate account can get all or a part of the special rights of the root account. Of course the root account cannot delegate more rights than it possesses itself.

The set of an organization’s subordinate accounts directly depends on the access rights of the root account, and the delegation of access rights can be done by switching on or off one or several items of the following:

  • Availability of special layers and access rights in the geodata mapper,
  • Availability of special products in the product catalog,
  • Functions to create and manage orders in the name of the organization,
  • Direct access to secured OGC webservices,
  • Functions to manage the organization’s products, orders and metadata.

4.3 Connect to the geoportal

On the upper left of the geoportal’s screen appears the login block.

If the user is not yet connected:
  • He can log in by typing his username and password

When connected, the user can:
  • Log off with the link «disconnect »
  • Manage the account settings with the link “my account”
  • Create and manage subordinate accounts with the link “subordinate accounts” (only in case this function is active)

4.4 Manage the “Subordinate Accounts”

Root accounts with active subordinate account function can create and manage subordinate accounts. This function is only available for the root account itself and not for the subordinate accounts.

FIXME

The management of the subordinate accounts has 3 main aspects:

  • Hierarchical organization of the accounts
  • Creation of a new account
  • Management of the account settings:
    • for the personal data
    • the authentication
    • the available functions

4.4.1 Hierarchical organization of the accounts

The subordinate accounts are organized in a tree-hierarchy, where the main branch directly depends from the root account. There can be as many sub-branches as needed by the root account.

FIXME

Between the root account and the subordinate account the special rights detained by the root account can be passed on totally or partially. But among the subordinate accounts the tree hierarchy is a purely organizational one. There is no transfer of rights from one level of the subordinate accounts to another.

The user of the root account can :

  • Select a particular account by clicking on the associated icon
  • Create a new account

4.4.2 Manage the settings - « Contact » tag

This tag is the first to be opened when a new account is created. The empty fields have to be filled. When an existing account is opened, the contents of the settings is displayed.

Unlike the root account, the subordinate accounts do no have a section for the billing address, as they always act on behalf of the root account’s organization. The billing address of the root account is automatically used.

The properties of the “Contact” tag are:

  • Identification of the contact person
    • Root : to be chosen in the drop-down list. It is the name of the account to which the new account will be attached in the hierarchy.
    • Name : personal name of the user
    • Contact : professional function of the user
    • Telephone : professional phone number
    • Fax : professional fax number
    • Email : professional eMail address
    • Url : professional website URL
  • Address of the contact person
    • Line 1 & 2 : address
    • Post code
    • Town
    • Country

The user can:

  • Validate the contact person.
    The field's content is tested and eventual errors are announced.
  • Go back to the list of subordinate accounts.
    The user is warned that the modifications will be lost and asked if he wants to continue.

4.4.3 Manage the settings - “Login” tag

The name of the user associated with the account is mentioned on the top of tags to make sure the root account user is well aware of which account he is actually dealing with.

The properties of the login tag are:

  • Identification of the contact person
    • User name : code which identifies the user in the geoportal. It has to be a string of at least 6 characters, and has to be unique in the system.
    • Password : contains the password asspociated to the the user name

      Here, the root account does NOT type anything.
    • New password : field to define a new password, or the first password in case of new accounts. The field is double, to make sure the password is correctly saved.

The user can:

  • Validate the settings
    After successful tests, the new account is created or the setting changes of the account are saved and activated
  • Go back to the list of subordinate accounts
    The user is warned that the changes will be lost and is asked if he wants to continue

4.4.4 Manage the settings - “Rights” tag

It has already been mentioned above that when creating new subordinate accounts, the root account can pass on all or part of its special rights to the subordinate accounts. To make things quite simple yet powerful enough, the geoportal offers transfer of rights with the following principles:

  • The root account can never grant more rights than it possesses itself. The following examples show cases where the root account does not have certain rights and where the corresponding checkboxes are inactive:
    • Case of a “customer”'s root account
    • Case of a root account that does not have access to webservices
  • The rights granted by the root account are always supplementary rights to the basic rights contained in the « general public » account. This means that when a certain part of the rights for a subordinate account are inactive, it always has as a minimum the rights of the “general public”. In case the root account activates certain rights, this means that the subordinate account possesses the same rights than the root account.
  • The transferable rights are grouped in 5 packages that can be switched on or off by the root account.

The following options can be activated:

  • See the maps : if this option is switched on, the subordinate account owns the same rights as the root account in terms of extended access in the mapper. This means that he may see more layers, have other scale restrictions and less other restrictions than the “general public”. If this option is switched off, the user has exactly the same rights and contents as the “general public”.
  • Products : if this option is switched on, the subordinate account owns the same rights as the root account in terms of extended access in the catalog.
  • Create and manage orders : if this option is switched on, the subordinate account’s user can create and manage orders on behalf of his organization.
  • Access to OGC webservices : if this option is switched on, the subordinate account can use secured webservices delivering geodata via OGC standards using the account’s user name and password.
  • Access to the provider’s functions : if this option is switched on, the subordinate account’s user can create and manage products on behalf of his organization as well as manage the corresponding metadata and incoming orders.

4.5 Manage the own Account (“My Account”)

After having logged in, every user can manage his account’s settings. This happens in the menu “my account”. Most of the functions are the same as those already described above for the subordinate accounts.

4.5.1 My account - “Contact” tag

The properties of this tag are the same as those described above. Aditionnally there are fields for the billing address.

The user can :

  • Validate the contact person
  • Cancel the changes

4.5.2 My account – “Login” tag

The properties of this tag are the same as those described above.

The user can :

  • Validate the contact person
  • Cancel the ongoing modifications

6. Consulting the product catalog - Function « Our Products »

In the menu “Maps and Products”, the function “Our Products” leads to the geoportal's product catalog:

This catalog opens on a static page, offering the choice between the different geoproduct categories and the multi-criteria search engine.

6.1 Searching for geoproducts by category

The following 3 categories are available:

  • maps
  • official extracts
  • specific products

In every category the products are listed in a catalog view:

The indicated information is :

  • name of the product
  • name of the provider
  • a link for the products that can be ordered online

The list is split into pages and can be sorted by:

  • name of the product
  • provider

With the multi-criteria search, it is possible to find available geoproducts by using different parameters.

In the alphanumeric part, the criteria are the following:

  • Name of the product
    1. Enter : string composed only by letters
    2. Message : [« The format of the product's name is not correct »]
      1. Wrong characters have been used
  • Name of the provider
    1. Enter : string composed only by letters, to be selected in the list
  • Name of the theme
    1. Enter : string composed only by letters, to be selected in the list
  • Date of the last update of the product
    1. Enter : string with the format [dd.mm.yyyy]
    2. Filter : default value is “equal”
    3. Messages : [« The format is incorrect »]
      1. Wrong characters used
      2. Separation forgotten
      3. Wrong number of characters
  • Special filter to show only the products that can be ordered online in the geoportal
    1. Enter : classic check box

Spatial search : A little mapping tool is offered to define the geographic extent of the search. This can be done by drawing a rectangle in the map.

The navigation in the map is done by the following geographic functions:

  • Zoom +/-
  • Pan (image translation) and arrows
  • Scale (same same function as in the mapper)
  • Loclizing on a local government's extent
    1. Enter: Choice in a drop-down list
  • Localizing on a town
    1. Enter: Choice in a drop-down list
  • Localizing on a parcel
    1. Enter :
      1. « Cadastral Commune »: drop-down list
      2. « Cadastral Section »: drop-down list
      3. « Main parcel number »: field
      4. « Secondary parcel number »: field
    2. Messages :
      1. [« Incorrect format»]
      2. [« This parcel does not exist »]
      3. the search does not succeed

Note: For the parcels which do not have any secondary number, it is automatically filled with 000000.

Note: For a parcel with the number 23/435, the user simply types 23 as main parcel number and 435 as secondary number. The fields are completed automatically.

The multi-criteria search presents the results in a list. Two buttons on the bottom of the page on the right allow to:

  • Go back to the initial blank search engine page with : New search
  • Start the search with : Start the search

In case no product is found that corresponds to the search criteria, the initial search page is opened and the user is warned about the negative search result.

6.3 Viewing the metadata of the geoproducts

The catalog contains detailed information about the different geoproducts that are available in the geoportal. They are produced by the different providers who cooperate with the geoportal. The information sets are called metadata.

The metadata sets are accessed via the list of the geoproducts, by clicking on the product’s name. They are opened in a separate window.

The contents of the metadata sets respect the ISO 19115 norm. A selection of fields, which have to be filled in by the providers for each product, has been made among those proposed by the norm. This means that in the scope of the geoportal, for the first time in Luxembourg, a “luxembourgish metadata profile” has been established. This profile can later be used to exchange metadata with national and international instances.

Like all the contents of the geoportal, the metadata sets are normally available in 4 languages. The user chooses the language by clicking on the flag-buttons.

With the button “XML” , the user can get the contents of the metadata set in XML format (ISO 19139).

With the button “PDF” , the user can render contents of the metadata set in a PDF file.

7. Ordering geoproducts - “Order” function

The customers of the geoportal have access to the functions to create online orders of geoproducts.

The general principle of orders in the geoportal are represented in the following picture :

The online shop can be accessed in the geoportal’s main menu :

The 4-step ordering process is launched by clicking on the button “To Order”.

The 4 steps are:

  • Selection of a geoproduct in the catalogue
  • Definition of the geographic extent of the order
  • Definition of technical and organizational parameters
  • Checking & Sending

7.1 Selecting a geoproduct

The selection of a geoproduct happens in the catalogue itself:
( → more informations in section 6)

First the overall product category has to be chosen, or a multi-criteria search has to be launched. The results of the search is a list of the products with the following information:

  • Name of the product with a link to the metadata
  • Provider
  • A caddie which contains a link to select this product and to continue with the next step of the procedure

The list is paginated and can be sorted following the name of the product or the providers.

Next to the links connected to the multi-criteria search (New search and Modify the search parameters), the user can :

  • Select a product which he wants to order by clicking on the icon which changes its colour:
  • Go on with the order : the geoportal saves the product choice and moves on to the next step

Shortcut : the user can do the selection more quickly by directly clicking on the wanted product’s name instead of the caddie. This automatically leads to the next step.

7.2 Definition of the order’s geographic extent

In the 2nd step, the user has to define the geographic extent on which he wants to order the selected product. To do so, the geoportal offers several “order extent types” among whose the user may choose. The number and sort of these extent types depend on the product. For example Act’s 1/20000 map is sold only following the fixed TC20000 map sheets.

To be oriented in the geography, a mini-mapper is available offering the most elementary navigation and location functions of the main mapper.

The “order extent type” is selected by a click on the corresponding button

If the user changes the extent type after a definition has already taken place, the procedure is initialized and a warning message appears :

Depending on the order extent type, the actions to be done can vary slightly. For this reason, in the following chapters every single order extent type is explained with its exact procedure.

7.2.1 Extent type "North-South Rectangle"

Rectangle
The extent type “North-South Rectangle” is easy to use. It is activated by clicking on the button “Rectangle”. Then the geographic extent is defined in the map by drawing the rectangle as shown in the picture : start on the upper left point, hold down the left mouse button, keep it down while moving the mouse pointer to the opposite point right below. Then release the mouse button. The map window shows the rectangle.
Steps to do
On the lower right side of the screen, the coordinates of the rectangle are listed:
Alternative steps to do
Instead of defining the order extent graphically, it is also possible to type the x,y coordinates of the rectangle.
The coordinates are considered to belong to the actually active coordinate system
After typing the coordinates of one point in the fields, the point is saved in the drop-down list with the button.
After defining the 2nd point, the rectangle is defined and can be drawn correspondingly.
The button can be used to delete the selected point from the list. 1.
2.
To go on with your order…
After having defined the order extent, the user can move on to the next step of the ordering procedure by clicking on the button

7.2.2 Order extent type "Polygon"

Polygon
The order extent type “Polygon” is activated by clicking on the button “Polygon”. Then the different vertices (points) that compose the polygon can be defined graphically in the map window with the left mouse button: every point is defined by a click on its location, and is drawn as a small filled square. This procedure is repeated as often as there are points needed to define the order extent.
Steps to go
On the lower right of the screen the coordinates of the points that have been defined, are listed in the drop-down list:
Finally, the polygon composed by the points from the list, can be validated with a click on the button. The polygon is drawn in red transparent colour in the map. This way a visual control of the order extent is possible.
Alternative steps to go
Instead of defining the order extent graphically, it is also possible to type the x,y coordinates of the polygon. The coordinates are considered to belong to the actually active coordinate system:
After typing the coordinates of one point in the fields, the point is saved in the drop-down list with the button
The button can be used to delete the selected point from the list
After defining the last point, the polygon is validated with the button and is drawn accordingly. This way a visual control of the order extent is possible.
To go on with your order…
After having defined the order extent, the user can move on to the next step of the ordering procedure by clicking on the button

7.2.3 Order extent type "Circle"

Circle
The order extent type “Circle” is activated by clicking on the button “Circle”. Then the dimensions of the circle can be defined graphically in the map window, using the left mouse button : first the circle centre is defined in the map, it is represented with a black square marker. Then a 2nd point fixing the circle radius is defined in the map with the same procedure.
Steps to go
After the definition of the 2nd point, the circle is drawn in red transparent colour. This way a visual control of the order extent is possible.
On the lower right of the screen the coordinates of the points that have been defined, are listed in the drop-down list,
and the radius of the circle is indicated in the unit “meters” :
Alternative steps to go
1. First define the circle centre like explained above
2. Then type the radius in “meters” in the field on the lower right of the screen:
3. Then validate with the button
After this validation, the circle is drawn in red transparent colour. This way a visual control of the order extent is possible.
To go on with your order…
After having defined the order extent, the user can move on to the next step of the ordering procedure by clicking on the button

8.2.4 Order extent type "Buffer"

A “Buffer” is a surface defined by a certain distance on both sides of a line. This can be useful when data is needed around linear axes like streets or rivers.

The order extent type “Buffer” is activated by clicking on the button FIXME. Then the line of the buffer is defined in the map by clicking the respective vertices in the map with the left mouse button. Every point is represented in the map as a black square.

On the lower right of the screen, the coordinates of the points defined in the map are listed in the drop-down list.

FIXME

After defining the line, the width of the buffer zone has yet to be fixed. The width in “meters” is entered in the field on the lower right :

FIXME

The buffer is validated by clicking on the FIXME symbol, and drawn in red transparent colour in the map for a visual control. After having defined the order extent, the user can move on to the next step of the ordering procedure by clicking on the button FIXME.

Instead of clicking the points in the map, it is also possible to directly enter their coordinates. These coordinates are considered to refer to the actually active coordinate system:

FIXME

With the button FIXME, the coordinated typed in the fields are saved in the drop-down list on the right side. The FIXME button can be used to delete the selected point from the list.

FIXME

After defining the line and the width of the buffer, the buffer zone is validated with the FIXME button and drawn in red transparent colour in the map to permit a visual control.

8.3 Specific properties of the order

After the product to be ordered has been chosen, a certain number of specific properties concerning the order request have to be fixed. This information enables the provider of the product to create and to deliver it conformingly. These parameters are entered in a form and the content of the form varies with the product. It is called “geoportal order form”. The following picture shows an example of the order form for the product “BD-L-TC complete (with attributes)“.

FIXME

The order properties are organized in 4 chapters :

The identification of the order or estimate request
  • Name of the order * : It is freely chosen by the customer in order to have a reference to his order which is easily recognizable.
  • Kind of request * : If enabled by the provider, the customer can either request an order or only an estimate.
The ordered data
  • Coordinate system * : Cartographic projection used to deliver the data. The choice is done in a drop-down list. If forgotten, the message « Please select a coordinate system » appears.
  • Data format * : Kind of file format used to deliver the extracted geodata. The choice is done in a drop-down list. If forgotten, the message « Please select a format» appears.
  • Operation system * : Operation system on which the data will be stored and used. The choice is done in a drop-down list. If forgotten, the message « Please select an operation system » appears.
  • Clipping mode : With this parameter the customer can choose between 3 options concerning the retrieval of the data to be delivered in the product in relation with the contour of the order extent.
    • With “Exclusively interior”, only the features that are completely inside the order extent without touching the limit, are delivered.
    • With “Interior and limits”, all features interior and touching the limits of the order extent are delivered, but those that touch the limit are clipped at the limit line.
    • With “Interior and crossing the order extent limit” all features that are inside the limit as well as those that touch the order extent limit are delivered entirely.
  • Group * : If several cadastral communes are ordered, they can be put together (grouped) in one single file, or delivered as separate files.
Delivery
  • Delivery method * : The media used to ship the product. The choice is done in a drop-down list.
Provider specific properties

Next to the properties already described, it is possible that the order form contains more fields to be filled out. Indeed the provider may need other information for his internal management of the orders, than the intrinsic parameters mentioned above, and he can add the corresponding fields to the order form. For this reason an entire section “specific properties” exists in the order form.

After providing all the necessary information in the order form, the customer may proceed to the last step with the button FIXME.

8.4 Order summary and sending the order or estimate request

FIXME

In the last step a summary lists all the parameters concerning the order or estimate request that have been fixed during the preceding steps The customer can check them before sending the request.

The customer can :

  • Save the order to keep it as a draft for later use (attention : then the order is NOT sent)
  • Send the order to the geoportal

In case the customer is not yet logged in the geoportal, the following message appears :

[« Please authenticate by providing your username and password in the login block on the upper left of the page. Your order will be saved temporarily and be kept available when your identification has been done. »]

Using his password the user can log into the portal, and his order will be available to send. But it is important to notice that authentication is only possible for users who have been granted a username and password previously by Luxembourg’s Cadastre and Topography Administration ACT.

The anonymous user « general public » does not have the rights to send orders in the geoportal.

8. Order: Function « Manage my orders»

The authenticated user can manage his orders in the geoportal.

The order overview is opened with the “Trace my orders” button in the menu “Order” :

8.1 Order overview

For every state, the number of requests is indicated in the overview.

If in a certain category no requests exist, the corresponding link is inactive and the indicated number is 0. The corresponding tag text is italic and the link is inactive.

By clicking on one of the active links either in the overview or in the tag titles, the corresponding tags are opened. They contain a table with the order and estimate requests of the category:

  • Draft : the order and estimate requests stored in this tag have not yet been sent, but only stored for later use,
  • Sent : contains all the order and estimate requests that have been sent by the customer and not yet been returned by the provider in charge,
  • Received : the order and estimate requests that have been finished and returned by the providers, and where the results have either been sent by post or made available for a download.
  • Archived : the order and estimate requests that have been received, and that the customer wants to keep for later use.

8.2 Requests in the tag « Drafts »

The order and estimate requests in the tag « drafts » are complete or incomplete requests that the customer decides to keep for later use. It is easy to use such a request to rapidly create a new request that can be sent.

The tag looks like this:

FIXME

The information presented in the list is:

  • Number of the request (with a link to the request summary)
  • Name of the request
  • Type of the request (order or estimate)
  • Name of the product
  • Saving date

The list is paginated and can be sorted by:

  • Request number
  • Request name
  • Type
  • Product name
  • Saving date

Based upon an existing request in the list, a new request can be generated by clicking on the button next to the request.

The customer can :

  • Click on

The following message appears:

« You are about to create a new order or estimate request based upon the selected request. Do you want to continue ? »

After validation with “OK”, the customer enters the 1st step of the order process. Every information in the 4 steps are kept an can be modified.

  • Click on the order number

The request summary is opened in an new window:

FIXME

8.3 “Sent” orders

  • Name of the product
  • Saving date

The list is paginated and can be sorted by:

  • Request number
  • Request name
  • Type
  • Product name
  • Saving date

Based upon an existing request in the list, a new request can be generated by clicking on the button next to the request.

8.4 “Received” orders

In the tag “received” the customer finds the requests after their treatment by the providers. If the result of the order is a downloadable file, the download is done in this tag by clicking on the symbol .

FIXME

The information presented in the list is:

  • Number of the request (with a link to the request summary)
  • Name of the request
  • Type of the request (order or estimate)
  • Name of the product
  • Saving date

The list is paginated and can be sorted by:

  • Request number
  • Request name

  • Product name
  • Saving date

Based upon an existing request in the list, a new request can be generated by clicking on the button FIXME next to the request.

The downloadable files are contained in one single archive file which can be opened by clicking on the symbol .

The following icons are used to inform the customer on the media used to deliver the ordered products :

  • CDROM or DVD : FIXME
  • Paper format : FIXME

The user can :

  • Click on the download link
    The following dialog box opens:

  • Delete a request
    The following confirmation message appears:
    « You are about to delete the request. Do you want to continue ? »
  • Archive the request
    The following confirmation message appears:
    « You are about to archive the request. Do you want to continue ? »

8.5 “Archived” orders

The customer con store his requests in his personal archive.

The information presented in the list is:

  • Number of the request (with a link to the request summary)
  • Name of the request
  • Type of the request (order or estimate)
  • Name of the product
  • Saving date

The list is paginated and can be sorted by:

  • Request number
  • Request name
  • Type
  • Product name
  • Saving date

Based upon an existing request in the list, a new request can be generated by clicking on the button next to the request.

For the archived requests, the downloadable files under the symbol remain available for a certain time before they are deleted. From the moment they are deleted, the link disappears but the information concerning the request remains available.

The user can :

  • Delete a request
    The following confirmation message appears:
    « You are about to delete the request. Do you want to continue ? »

9. Order : Create a new order from an existing order or estimate request

In the “draft”, “sent”,“received” and “archived” tags of the order overview it is always possible to launch a new order based on an existing order or estimate request in one of the lists.

This can be helpful when doing multiple orders with small differences in the parameters.

The following paragraphs describe the procedure to follow.

In the list, click on the link corresponding to the order you want to base the new order upon.

The following message appears:

After validation with “OK”, the first step of the ordering procedure is launched:

In this step it is possible to select another product.

If you do not want to select another product, you can immediately go further to the following steps:

  • With a click on , you open the geographic range selection menu
  • With a click on , you enter the order form
  • With a click on , you open the final verification and send menu

In each step, the original settings of the order can be modified.

For example, in the order form (step 3), the fields are still filled with the original content, but can be modified to suit the new order. This way, a series of orders can be created very easily and efficiently, which may be useful especially when only few settings differ from one order to another (f.ex. order in shape format, dxf format and dwg format).

In terms of proper organisation, it may be useful not to forget to change the order name.

10. Order: Function "Archive"

An authenticated customer can use the search tool to find old requests. This is done by clicking on the “Archive” button in the “order” menu :

The search screen offers the following parameters:

  • Provider (list)
  • Product (list)
  • Type (order or estimate), (list)
  • Order state (list)
  • Sending date
  • Reception date

After the search, the presented information is:

  • N° of the order with a link to the order summary
  • Product name
  • Request type (order or estimate)
  • Provider of the product
  • Current request state
  • Reception date
  • Sending date

11. Functions of the "Product and data provider"

The product and data providers that are linked to the geoportal generally have the following possibilities in the system:

  • They can insert products of their own in the geoportal's product catalog, even if these products cannot be ordered or are not available. These metadata can be inserted directly in the geoportal, using the provider's root account or a sub-account duly validated for this task and the corresponding product. The function for this actions is named “Create metadata”.
  • They can offer their own products for sale. To do so, they first have to announce and to configure these products within the geoportal. This can be done using the function “Manage products”.
  • See and handle the incoming orders of their products. This can either be done within an external automatic work flow application, or manually in the portal itself. These actions concerning the orders can be done using either de provider's root account or using a sub-account which has been previously habilitated to this extent. The corresponding function is “Handle the orders”.
  • Provide geodata layers to be shown in the mapping tool of the geoportal. However this integration of new data in the mapping tools cannot be done by the provider himself and needs actions to be undertaken by the system administrators.
  • Providers can also create geodata webservices and have them integrated in the geoportal's access control system. This way the external geodata provider can benefit from the security layer provided by the geoportal. To achieve this integration, mutual collaboration between provider and geoportal administration team is necessary.

11.1 Function "Handle the orders"

A product and geodata provider of the geoportal, who offers products for sale in the geoportal, can handle the incoming orders of his products principally in two ways:

  1. He can build up a separate IT tool that connects to the geoportal, regularly scans the geoportal's database for incoming orders of the providers' products, and retrieves those orders for a completely or partially automatic treatement. When the orders have been successfully concluded, either automatically or manually, and when they reach a final status, the orders and the related information (prices, modifications, remarks etc) are reinserted into the geoportal and eventually downloadable files are uploaded onto the geoportal-servers to be downloadable by the user.
    The “administration du Cadastre et de la Topographie”, in its role of provider, uses such a workflow system to handle its orders.
  2. He can deal with the orders in a very simple way by using the geoportal mainly as a communication tool with the user. This means he creates the ordered product manually, but uses the geoportal to change the order's status, to indicate the price and even to upload downloadable content. This means that the geoportal's platform is also available to actors who do not have the size or means to invest in a heavy-duty software application, but who think it is interesting to be present on the geoportal. The manual handling of the orders is also a good back-up possibility for providers with automatic order processing, in case of downtime.

The following paragraphs explain the tasks of the providers concerning the incoming orders and estimate requests, in the case the orders are processed directly within the geoportal.

The tasks are:

  • create a price estimate,
  • prepare an order,
  • upload the order on the portal.

To process the orders, click on “Handle the orders” in the menu “Providers”, in the function bar on the left of the geoportal page:

When this function il launched, a control panel of the ongoing orders, grouped by status, is displayed.

11.1.1 Order control panel

The order control panel indicates the active orders for each order status, either “to be processed” or “completed”.

The appearance and the handling are identical to the order control panel. Click on one of the status tabs or links to open the corresponding table containing all the orders in the selected state:

  • To be processed : the orders received from the customers and that have not yet been completely processed,
  • Completed : the orders which have been completely processed and that are closed.

11.1.2 Orders " To be processed "

The tab of the orders to be processed looks like shown in the following picture:

The information shown in this list is:

  • Order number (with a link to the order summary)
  • Order name
  • Order type (estimate or order)
  • Product name
  • Reception date

The list is split into pages and can be sorted by:

  • Order number
  • Order name
  • Order type
  • Product name
  • Date

The user can

  • Click on the order number …
    A page is opened with the order summary which has been saved when the order has been sent

… or click on an icon to open and process an order:

  • Click on the icon FIXME which specifies the order type and state
    A page is opened and displays fields to type the requested information
  • Click on the upload icon FIXME to proceed to the upload dialog

11.1.3 Orders with the status "Completed"

The information shown in the table is:

  • Order number (with a link to the order summary)
  • Order name
  • Order type (estimate or order)
  • Product name
  • Date of processing

The list is split into pages and can be sorted by:

  • Order number
  • Order name
  • Order type
  • Product name
  • Date

The user can click on the order number (link) to open the order summary which was saved when the order was sent.

11.1.4 Order summary

Apart from the order details, the provider can find information about the customer, as it is shown in the picture below.

The information listed about the customer is:

  • Name of the customer,
  • Role,
  • Telephone number (if available),
  • Fax number (if available),
  • eMail address,
  • URL of the customer's website (if available).

The user can:

go back to the order control panel
go back to the list of orders to be processed
go back to the list of the processed orders

11.2 Manual processing of an order

In the following paragraphs it is described how to manually process an estimate request or an order in the geoportal:

11.2.1 Estimate

If the product provider has specified in the product settings that it is possible to require estimates of the product, the customer can use this possibility. When the provider has entered a price in the geoportal, this figure appears in the order summary, which then can be viewed by the customer after its updating.

Properties of the estimate:

  • Price : This is the price VAT included of the ordered and delivered product

The following messages can appear: “Please type a price for the order” → The provider has not yet typed a price “The price format is incorrect” → invalid characters

  • Remark : it is possible (optional) to add remarks that are related to the order.

11.2.2 Order

The manual processing of an order in the geoportal is similar to the processing of an estimate: click on the order number to open the corresponding dialog box.

Order properties:

  • Price : This is the price VAT included of the ordered and delivered product

The following messages can appear: “Please type a price for the order” → The provider has not yet typed a price “The price format is incorrect” → invalid characters

  • Remark : it is possible (optional) to add remarks that are related to the order.

11.3 Function "Manage the products"

The product management tools are only available for user root accounts that have the status of a provider in the geoportal. With these functions, that are available under the main title “Provider”, it is possible to create, modify and manage the provider's own geoproducts in the geoportal. The main point

When the function “Manage the products” is launched, a table is opened with all the products of the provider. The contents and type of display are similar to the order control panel, also in terms of sorting functions.

The user (root account) can either select and open an existing product by clicking on the corresponding link in the list (for example to modify some settings of a product) or create a new product by clicking on the button “Create a new product” right on the bottom of the page.

When a new or an existing product is opened, a new page displays with 3 tabs:

  • Definition
  • Responsibility and visibility
  • Order form

In these 3 tabs all the definitions of a product in the geoportal are done. In case of a creation of a new product, the user has to go through all 3 of them in order to specify the parameters needed for the definition of the product.

11.3.1 The definition of the product

The first tab contains all the main product definitions.

The following parameters have to be specified:

  • Product number : this internal number is automatically allocated.
  • Code : the product code is a free string character chain to be defined by the provider. It has to be unique, as it is used to ensure the connection to external order processing tools.
  • Category : for a better overview of the products, they are classified in 3 main categories: the maps, the official extracts and the specific products. The provider has to decide, to which category his product should to be allocated.
  • Estimate or no : the provider can check the box if he wants to allow estimates to be orderd. If the box is unchecken, the customer cannot require estimates of the product.
  • Reference language : the provider chooses among the proposed 4 languages
  • Product name : to be defined in the 4 system languages
  • Available order extents : in this part, the provider activates by checkboxes the geographic order extents that should be available when his product is being ordered by a customer in the geoportal. In the fields behind the order extents a minimum/maximum number of items or square kilometers (in case of extents based on polygon definition) can be defined.

11.3.2 Responsibility and visibility

In the 2nd tab, the provider specifies the users within his organisation to which a certain responsibility of the product evolution in the geoportal is delegated. There he also decides about the visibility of the product.

He first specifies which user is responsible for the manual processing of incoming orders within the geoportal.

In the visibility part, he decides if the product can be orderd only within his own organisation (internal product), or if it can be ordered by anyone. The first option may be useful when new products are announced, to check and verify if the specifications are OK.

11.3.3 Order form

In the 3rd tab, the provider can define, modify and complete the order form to be used by the customer during an order procedure.

The order form consists of fields organised in a certain structure, designed to contain all the necessary information the provider's organisation needs to create the product. As every product has different specifications, this order form can be modified online by the provider in order to satisfy his needs.

The following pictures taken from an order form of a product of ACT, shows the structure of a form.


Several fields are mandatory for the system to work, independently from the product's specifications. Those fields cannot be deleted. In several sections it is however possible to interactively add new fields.

To configure the contents of a drop-down list of a field, f.e. of the field “Coordinate system”, click on the icon FIXME next to the field. The following dialog box opens:

With the buttons », >, <, «, the elements can be inserted or deleted from the list “selected values”, and by this means, the drop-down list can be edited:

The procedure is similar in all the cases, where the contents of a list has to be modified. Next to the mandatory fields, it is also possible to add personal fields in the form. To do so, click on the icon FIXME next to the section, where a new field has to be added. The creation of a new field happens in 3 steps:

Step 1 : Choice of field type

Step 2 : Contents in 4 languages and values

Step 3 : Summary.

Except from the mandatory fields, fields can be deleted from the order form by clicking on the icon FIXME. It is also possible to edit the field definition by clicking on the icon FIXME.

11.4 Function « Manage the metadata »

11.4.1 Why are there metadata ?

Metadata are textual information sets concerning geodata, webservices, products derived from geodata and layers in the mapping windows. They describe key elements like definition, whereabouts, actuality, quality, price, availability, responsibility etc.

Why do the providers have to type metadata in the geoportal ?

Geographic data in the geoportal is a digital representation of items of the real worls, used to show, analyse or otherwise use them in an IT environment. The use of geodata in many different fields of action is more and more widespread, and it has become easy to produce, modify and use this data. But it is important to know that these geodata are a more or less “imperfect” abstraction of the real world phonomenon, and not an exact duplication. To be sure that they are not used ina wrong context and to prevent eventual damage due to their use, it is important to provide all necessary information to the potential user, to give him the opportunity to evaluate if the geodata may convene to his needs.

11.4.2 The ISO 19115 norm

The ISO 19115 norm defines a structure to describe digital geodata. It fixes the mandatory elements, the terms, definitions and procedures of this information. With its norm compliant metadata catalog, the geoporta offers a unique and central platform for the providers to describe their data and products in a standardised way. The metadata of the national geodata can be organised and managed efficiently, and users can obtain all necessary information to be able to use the data. What's more, discovery of data and products becomes much easier.

11.4.3 Metadata editing

The provider has access to the metadata editing functions. In the menu “Provider”, the button “Metadata management” leads to the list of metadata draft sets the provider actually is working on.

The user can either click on “Create a new metadata set” to open the creation dialog and work on a new metadata set, or he can click on one of the icons next to an existing metadata drafts to - delete it - launch the INSPIRE conformity validation check - print it as a PDF document - render it as an XML file - send it to the geoportal and ILDG managment team to validate the metadata set and to insert it into the catalog - edit the metadata draft - crate a new metadata draft set based on the existing one

In the metadata editor, 9 tabs contain a long list of fields, compliant to the ISO norm, and selected to satisfy the INSPIRE needs as well as the national needs. They can be filled out depending on the field type : either free text or choices from lists or checkboxes.

The metadata draft can be saved, and exists as metadata draft set as long as no validation has been requested. It can be edited by the provider, modified, deleted and used as base for new draft sets. Using the icon FIXME the set can be sent to the geoportal management team for validation. In case validation occurs, the metadata set is activated in production and no longer available in the list of draft sets of the provider. He always can access his metadata set in the public catalog and either copy it or generate a new version, if he wants to update it.

12. Publication of own geodata layers in the mapping tools

Providers of the geoportal can have their own geodata published in the mapping tools of the geoportal.

Quite contrary to the creation of new products, this publication cannot be done autonomously by the provider. Indeed the system architecture needs the interaction between both the provider and the system administrators.

The following steps are necessary:

12.1 Agreement about the layers to be published

When a provider wants to publish own geodata layers, he decides together with the responsible persons at ACT about the access conditions to his data in the mappers. He also decides about the names of the layers in the 4 languages, and about the main themes the layers should be classified in.

These decisions are added to the written common agreements between ACT and the provider.

12.2 Norm compliant webservices

Providers should create OGC compliant webservices of their geodata (WMS) and give ACT access to them. ACT uses the webservices to add the data to the mapping tools

- by integrating the webservices in the “old” mapping tool (RedSpiderWeb technology)

- by using the webservice to calculate tile caches for the general public viewer map.geoportail.lu

In case of technical problems, ACT may offer its help to create the webservices. If no technical means exist at the provider's organisation, it is also possible to deliver the data to ACT. In this case, the geoportal department creates the webservices and does all the necessary actions to publish the geodata.

13. Publication de own geodata layers via the access control system of the geoportal

Each provider of products and geodata can publish own geodata webservices and use the access control layer provided by the geoportal webservice proxy.

For a better understanding, the difference between viewing geodata layers in the geoportal's online mapping tools and retrieving geodata contents via online access to webservices should be explained:

Whereas the mapping tools are designed to run within an internet browser - with the duly reduced functionality palet - the geoportal also offers an interface for professional GIS applications to directly connect to the geodata via standardized webservices.

This connection is only possible if

  • the customer has the necessary credentials, and
  • if the customer uses a GIS application that is able to connect to standardized OGC WMS (Web Map Server) or WFS (Web Feature Server) services.

The geoportal offers a great choice of webservices, part of which are protected by ghe geoportal's internal access control system. Of course every provider is free to publish his geodata independently from the geoportal, but he can also choose to integrate his webservices with the access control layer of the geoportal, instead of investing himself in such a system. In this case, his webservices are published with an URL of the geoportal, and they are accessed via the geoportal's “OGC proxy”.

This connection to a proxy can actually be done for WMS services as well as for WFS services.

The geodata webservices can be made available either to the general public, or to a precisely defined target user. This happens through detailed OGC access profiles in the geoportal's management system. The restrictions to be implemented in the profiles are decided by the provider and ACT in common.

This publication of geodata content via the OGC proxy can of course not be done by the provider himself. It needs co-operation between the data provider and ACT.

The steps to publish new geodata layers via the geoportal are the following:

13.1 Agreement about the geodata layers to be published

When a new user joins the geoportal as geodata and product provider, he decides together with the responsible persons at ACT which geodata layers he wants to publish on form of an integrated WMS or WFS webservice, as well as the possible restrictions he wants to be applied upon his webservices. There may be supplementary issues to discuss, like for example the possibility to allow reprojections in other SRS by the proxy, or the data rendering in different file formats.

These decisions can be documented in the written agreement which is signed between the representatives of ACT and the provider organisation, when the user account is opened.

The access restrictions that can be offered by the geoportal for the “proxied” webservices, are the following:

  • Layer visibility limited to certain users (per root account), or only accessible to the provider's organisation.
  • Layer visibility limited to a certain scale range
  • Layer visibility limited to a certain geographic extent (BBox, or polygon)

The provider can always ask ACT to change the settings of the access restrictions. In this case, the written agreement has to be adapted.

13.2 Mise en place de webservices de géodonnées normalisés

Le géoportail est entièrement construit sur la base d'échanges de données selon des spécifications et normes en vigueur, notamment sur l'utilisation de webservices normalisés basant sur la spécification WMS (Web Mapping Server) de l'OGC (Open Geospatial Consortium).

Pour publier un tel webservice à l'aide du proxy WMS du géoportail, le fournisseur doit d'abord mettre en place un tel webservice conforme à la spécification WMS. Il a le libre choix des softwares propriétaires ou open source qu'il entend utiliser pour ce faire. L'essentiel est la capacité du service de répondre aux appels normalisés selon la norme WMS.

Il doit ensuite fournir à l'ACT les informations nécessaires pour accéder ce webservice, comme l'URL et les données nécessaires pour la sécurisation (mot de passe). L'ACT procédera à des tests d'intégration du webservice, en respectant les spécifications retenues dans la convention sus-mentionnée.

L'ACT pourra essayer d'assister le fournisseur dans la résolution de problèmes relatifs aux webservices OGC.

13.3 Intégration du webservice dans le proxy WMS/WFS du géoportail

Après avoir effectué des tests concluants, l'ACT ajoute les nouveaux webservices en provenance du fournisseur dans le proxy WMS du géoportail.

Les nouvelles couches pourront être accédées de la même manière que les autres webservices disponibles, moyennant protection par mot de passe.

14. Informations techniques concernant la mise à disposition de webservices par les fournisseurs

Comme il est mentionné au chapitre 6.2 du présent manuel, le guichet cartographique est alimenté par des couches de géodonnées provenant de webservices normalisés qui reposent sur les spécifications WMS (Web Mapping Server) et WFS (Web Feature Server) de l'OGC (Open Geospatial Consortium). D'autre part, les géodonnées peuvent aussi être fournies directement via des webservices accessibles à des applications SIG clientes, tel qu'il est décrit au chapitre 7.

Dans le présent chapitre, les différents aspects quant à la mise en œuvre des webservices WMS pour le guichet cartographique ou le proxy WMS du géoportail sont explicités.

Le texte décrivant la spécification WMS est téléchargeable sur le site http://www.opengeospatial.org/standards/wms. Cette spécification a été reprise par l'ISO sous la norme ISO 19128.

Qu'est-ce qu'un service WMS ? Un service WMS est une application informatique tournant sur un serveur connecté à un réseau informatique (comme p.ex. un intranet d'entreprise ou plus généralement l'internet), qui fournit sur demande, et de manière dynamique, des cartes contenant des données spatiales à partir d'informations géographiques (ou géodonnées). Ce rendu graphique des géodonnées se fait à travers un fichier informatique dans un format utilisable pour un affichage à l'écran, généralement des fichiers image raster comme les PNG, GIF ou JPEG. Le fichier contenant la carte ne représente PAS les données elles-mêmes ! Par contre il peut être utilisé pour un affichage dans l'application cliente.

Comment fonctionne un service WMS ? La norme WMS définit trois opérations de base dans le fonctionnement du service WMS. La première opération s'appelle “GetCapabilities” et permet à tout client qui s'adresse au webservice d'obtenir toutes les informations techniques (metadonnées) sur le contenu que peut fournir un webservice, ainsi que sur des paramètres techniques comme le format des fichiers fournis, le système de projection cartographique, l'étendue géographique disponible, le genre de données etc.

La deuxième opération s'appelle “GetMap” et elle permet de demander au webservice de produire un fichier contenant une carte, en lui spécifiant l'emprise géographique (la “BoundingBox”, càd l'endroit géographique défini par un rectangle Nord-Sud, à travers les coordonnées des points-limite), le système de projection, les couches de données ainsi que des paramètres techniques variant selon le besoin (p.ex. taille de l'image rendue, transparence et couleur de l'arrière-fond). Un exemple d'une telle “requête” au webservice peut être :

http:\\ecadastre.public.lu:8081/public/wms/pcn?VERSION=1.3.0&REQUEST=GetMap&CRS=CRS:84&BBOX=97.105,24.913,8.794,36.358&WIDTH=560&HEIGHT=350&LAYERS=(…liste des noms des couches…)&STYLES=&FORMAT=image/png&EXCEPTIONS=INIMAGE

La troisième requête de base est l'opération GetFeatureInfo, qui permet de demander des informations alphanumériques (attributs) sur des entités graphiques (features) particulières représentées sur la carte.

Un WMS organise les contenus livrés sous forme de “couches”, et peut offrir des “styles” de représentation graphique différents, au choix du client qui invoque le service.

Le fournisseur a le libre choix des softwares propriétaires ou open source qu'il entend utiliser pour ce faire.

Il doit ensuite fournir à l'ACT les informations nécessaires pour accéder ce webservice, comme l'URL, et les données nécessaires pour la sécurisation (mot de passe). L'ACT procédera à des tests d'intégration de ces géodonnées, en respectant les spécifications retenues dans la convention sus-mentionnée.

L'ACT pourra essayer d'assister le fournisseur dans la résolution de problèmes relatifs aux webservices OGC.

15.2 Services of the geoportal

15.2.1 Target group

  • The geoportal is destined to :
    • national and foreign public administrations of state, regional or municipality level
    • societies and business companies that need geodata
    • the general public

The geoportal is an exchange platform of geodata, geoproducts and geodata webservices.

  • Are considered as geodata digital content with a unambiguous spatial link. Are considered as geoproducts all sorts of documents like maps, plans, extracts or others, which are based on geodata. Are considered as geodata services informatic applications capable of service geodata content on demand via the network.

15.2.2 Metadata catalogs

  • The geoportal contains a catalog with metadata about the available geoproducts, geodata and geoservices.
  • Every item is described in the catalogs with metadata which are compliant to the international specifications and norms in the geodata field.
  • The information about the available geoproducts, geodata and geoservice are managed by the different providers connected to the geoportal, and this information can by no means imply any responsibility of ACT, manager of the system.
  • Metadata found in the catalogs can never overrule legal stipulations (laws, règlements grand-ducaux). In case of loopholes in the catalog or contradictions between catalog and law text, the official legislation always overrules information contained in the catalogs.
  • The catalog contains information in 4 languages :luxembourgish, french, german and english. ACT cannot assume any responsibility in case of translation mistakes or eventual contradictions between the different language versions of the metadata sets.

15.2.3 Online geodata viewing

  • The geoportal offers a viewing tool to display geodat content concerning the territory of the Grand-Duchy of Luxembourg.
  • The content viewable in the mappers may not be used as legal proof in lawsuits. The content of the visible geodata, their completeness, actuality, precision, dimension or quality can never give any guarantee about the real circumstances in the terrain. ACT as well as the geodata providers of the geoportal deny any responsibility in case of eventual contradictions between the reality and the geodata content, even in case of damage encountered because of these differences.
  • ACT does not pretend to offer all existing official geodata content of the Grand-Duchy. But ACT aims at gathering as much ass possible of the available geodata.

15.2.4 Online order of geoproducts

  • Authenticated users can order geoproducts offered in the geoportal and require estimates of geoproducts.
  • Only registered users with a user account and a password can use the ordering function.
  • Any action made with a user account and its password implicates the responsibility of the account owner. This is especially true for orders.
  • The account owner has to take care not to disclose his account name and corresponding parties to thirds.
  • Ordered downloadable digital content remains available for download during 7 days after the first download to make sure that the customer can retrieve his data even in case of network problems. After 7 days, the files are automatically deleted.
  • Files which have not been downloaded are automatically deleted from the servers after 1 year, without notification nor refund.
  • In case of epayment, the customer has to comply to the rules of our partner companies CETREL and saferpay.

15.2.4.1 Conditions spécifiques relatives à l’acquisition et l’utilisation de données cadastrales

  • L’utilisateur confirme avoir pris connaissance du format d’échange des données pour lesquelles il sollicite, par sa commande, une concession de droits d’utilisation auprès de l’administration. Aucune réclamation ultérieure portant sur le fait que le format des données choisi soit inadapté au besoin de l’utilisateur ne pourra être prise en compte.
  • L’administration se réserve le droit de mettre à jour les données sans en avertir l’utilisateur, qui par la suite n’aura aucun droit de dédommagement, ni de remplacement des données.
  • Toute transmission de données à un tiers se fait sous la seule responsabilité de l’utilisateur et soumet ledit tiers aux mêmes prescriptions que l’utilisateur.
  • Si l’utilisateur ne demande pas un devis avant sa commande, il accepte implicitement le prix de vente fixé par l’ACT pour les données commandées.

15.2.5 Direct access to geodata content through standardised webservices

  • The geoportal offers a series of standardised webservices to deliver geodata online to the users.
  • Access to geodata webservices can be protected by an authentication with password.
  • The webservices are strictly compliant to the actual norms and standards, particularly the ISO standards and the Open Geospatial Consorium (OGC) specifications WMS, WFS, WCS, CS-W.
  • Neither ACT nor the other providers can guarantee that the webservices correctly interact with the client software of the users. No modification, configuration or adaptation can be required in case of problems.
  • The user has to acknowledge that the use of webservices is inclined to generate significant data flow and important server load. Therefore he has to prevent excessive use of the webservices.
  • Access to certain webservices can entail fees.

15.2.6 Special functions for geodata, product and webservice providers

  • The geoportal is a national exchange platform for geodata, geoproducts and geodata webservices, from multiple providers.
  • The geoportal offers several functions to
    • offer products in the eShop
    • publish geodata content in the mappers
    • provide metadata information about geoproducts, geodata webservices and geodata in the catalogs
    • receive and handle orders
    • manage orders
  • Access to the providers' functions presupposes an authentication with login and password.
  • The use of the provider functions is free of costs.
  • ACT assumes no responsibility in case of eventual problems in the interactions between customers and providers concerning orders made in the geoportal.

15.3 Prices

  • The use of the geoportal itself is free of costs, but ordering products or accessing webservices may entail costs, in conformance with legal dispositions.

15.4 Responsibility

  • By using the geoportal, the user implicitly agrees that ACT has met its obligations concerning advice and information about the essential caracteristics of the provided functions in the geoportal, and that ACT installed sufficient IT and telecommunication means to use the services.
  • Offering a support does not imply an obligation of a result.
  • Neither ACT nor the “Centre des Technologies de l'Information de l'Etat” CTIE can be made responsible in case of unavailability of the system or a malfunctioning internet connection, or in case of service disturbances due to technical reasons out of their reach.
  • Access to the geoportal is not guaranteed. ACT reserves the right to temporarily take the system offline, particularly of maintenance and security reasons. Such an unavailability implies no right whatsoever for compensation for damage suffered.
  • ACT takes all necessary precautions to avoid perturbances and damage through internet attacs, and to avoid taht harmful software penetrates the geoportal's IT infrastructure. Nevertheless no guarantee in this extent can be given, and ACT assumes no responsibility in case of eventual damage encountered because of such problems.
  • Neither ACT nor CTIE accept any responsibility in case of indirect damage encountered, lite financial or commerial loss, loss of customers or market parts, general commercial problems, cost rise, benefit diminution, brand mark loss, loss of data, files or programs, resulting from difficulties using the geoportal's services or from using the transferred information. Any legal action against the user by a third person is considered an indirect damage, and is not liable for damage compensation
  • ACT is not responsible for consequences resulting from the loss, theft or abuse of the user name and password in the geoportal.
  • ACT reserves the right to block user accounts if abusive actions are discovered.
  • The system can be configured to the personal needs of a user. But it is not allowed to proceed to forbidden actions in case of a malfunctioning access control.
  • Access to the geoportal's functions happes through internet. By using it, the user declares to knwo about and to accept its risks. He needs to protect himself against internet piracy through a securised IT configuration, especially a firewall and a virus check. Luxembourg State cannot be responsible of direct or indirect damage encountered through navigation on the geoportal.
