The purpose of the dataset is to present depth and terrain variations in the Oslofjord. Based on the bathymetry model, other terrain parameters can be calculated.

Bathymetry is closely linked to seabed geology and submarine processes, and is one of the most important parameters in the marine environment. Depth has a lot to say for water temperature, salinity, light conditions, currents, oxygen content, etc. which in turn affect biological and chemical processes in the ocean. Water depth and bottom relief are also of great importance for human activities at sea: transport, aquaculture, installations on the seabed, development, etc.

The data set can be used to present depth and terrain variations in the Oslofjorden for modeling and terrain analyzes, as a basis for area and environmental planning, habitat mapping, vulnerability analyzes, etc.

Although with good resolution (1m) the dataset is of rather poor quality. It is combined of several surveys and has holes and artefakts. Not suited for navigation. Best used at scales 1:100 000 - 1:10 000.
