Geonorge is the national catalog and access point for geographic information in Norway, coordinated by the Norwegian Mapping Authority (Kartverket). It brings together data from across the Norwegian public sector under the Norway Digital (Norge digitalt) cooperation.
The portal covers topographic base data, elevation and depth models, property and cadastre, place names, and thematic environmental layers. Many datasets are open under the Norwegian Licence for Open Government Data (NLOD) or CC BY, and are available both as downloads and as OGC web services for direct mapping.
