Bathymetric Data and Terrain Models of the Seabed

The Norwegian Hydrographic Service's map catalogue is part of Geonorge gives an overview of public geodata in Norway, map catalogues, and access to download data and APIs.

The Norwegian Hydrographic Service's marine geospatial data:

  • Marine primary data
  • Hydrographic survey data
  • Bathymetric data
  • Digital terrain models. Regular grids: 5x5 meters, 25x25 meters and 50x50 meters
  • Depth contoure lines
  • Charts, raster format, georeferenced

Data inside the territorial limit of 12 NM are subject to military restrictions.
