separasjonsmodell oceans
Current version: 2025a. New versions will be published as the underlying dataset is
improved. This model gives the vertical separation between NN2000 and the Norwegian chart
datum on a regular geographic grid (0.005° × 0.01°), covering the coastal region of
Norway. NN2000 is the reference level for heights on land, while chart datum is the
reference level for depths in nautical charts. The model is made by calculating the
difference between HREF2018B and the model for chart datum above the ellipsoid.

An estimate of the standard deviation of the model is included as a separate band in the GeoTIFF file. When selecting the bin-format, one gets a separate file with the gridded standard deviation.
