A geoportal is an information system that is based on geographic data. If collected and generated geodata shall be made accessible for various interested parties, we recommend the implementation of a geoportal. A geoportal can be accessed via the internet/intranet from almost anywhere, only a browser is needed. There is no need to install special software.

Different user groups can have different rights when accessing the geoportal, so you can decide which information the users can see.


Geoportals can be implemented individually for many different areas of application. GTA GeoService GmbH is experienced in implementing 

Do you need a geoportal for another application of geodata? Please contact us and describe your request!
