separasjonsmodell
Current version: 2025a. New versions will be published as the underlying dataset is
improved. This model gives the vertical separation between Mean sea level and chart
datum on a regular geographic grid (0.005° × 0.01°), covering the coastal region of
mainland Norway.

For most of the coast this model is equal to the model for Mean sea level above LAT.
From the island Utsira to the border of Sweden, Chart Datum is 20 cm below LAT, while
in the inner part of the Oslo fjord, Chart Datum is 30cm below LAT.

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.
