15.2 Services of the geoportal


15.2.1 Target group

The geoportal is destined to :

  • national and foreign public administrations on 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.

Is considered as geodata all 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.
In the catalogs every item is described with metadata that are compliant to the international specifications and norms.
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, the 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 :luxemburgish, 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 map portal to display geodata content about the territory of the Grand-Duchy of Luxembourg.
The content viewable in the maps 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 - shop

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 shopping 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 passwords 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.

15.2.5 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.
