Regular grids with 50m x 50m resolution which show the terrain variation on the seafloor in Norwegian sea/ocean areas. The grid model was generated by interpolating the original depth data from the primary database of the Norwegian Mapping Authority Hydrographic Service. Therefore the data has varying quality with regard to the reliability of both the positions and the depths.

The depth model is a regular bathymetry grid for the inner Oslofjord. The basis for the dataset is detailed depth data collected using interferometric sonar and multi-beam sonar.
