For developers

Geonorge has several APIs available to the users of Geonorge. The software code and accompanying documentation for most Geonorge tools are also available as open source code at GitHub.


APIs – application programming interfaces

Geonorge has numerous kinds of data and information sources. These can be accessed through APIs – application programming interfaces. Software developers can use APIs for direct access to data sources, and to make applications more functional and user-friendly.

These APIs are a collection of rules on how to execute requests relating to data and information sources, and they describe how different requests may give responses with different data selection variants.  APIs can usually be linked, making it possible to join data requests and ensure richer use of the information and data available in the Norwegian spatial data infrastructure.

The following Geonorge APIs are available: 

  • APIs for the Norwegian metadata catalogue
  • APIs for the Norwegian Feature Catalogue
  • APIs for the Geonorge/Norwegian NSDI registers – registry services
  • API for the Geonorge/Norwegian NSDI service validation and status function
  • Norwegian Geoportal Atom Feed
  • Norwegian Geoportal metadata service – CSW (catalogue service web)
  • Norwegian Geoportal metadata API – rest
  • ID references and linked data
  • Norwegian Geoportal download API
