Sediment data show mainly the prevalence of soil types covering the bedrock surface. Most of the soils were formed during and after the last ice age. The data shows only the soil that dominates in the upper meters of the terrain surface. Thick and thin layers by other soils may occur further down in the soil profile.

The map application shows geological themes NGU have available and which are of interest within the planning process when it comes to the field of Landscape, Resources and Safety.

Seabed sediments (grain size) show the grain size composition in the upper part (upper 0-50 cm) of the seabed. The dataset series comprise three datasets: Seabed sediments (grain size), overview, Seabed sediments (grain size), regional and Seabed sediments (grain size), detailed. The three individual datasets are digitized in different scales and have different data coverage.

The map layer shows grain size composition in upper part of seabed sediments (upper ca 50 cm of the seabed). Grain size as a property describes the percentage of different grain size classes in a sediment or superficial deposit type. The maps are digitized with a view to presentation at a scale of 1:20 000 - 1:150 000 (detailed mapping).

This dataset contains the grain size composition of seabed sediments upper part. Grain size data are based on analyzes of seabed samples, analysis and interpretation of digital reflectivity data and interpretation of analog and digital seismic data. In the attribute table of the data set, information is given about the different grain size classes based on the content of different fractions in sediments.

The map layer shows grain size composition in upper part of seabed sediments (upper ca 50 cm of the seabed). Grain size as a property describes the percentage of different grain size classes in a sediment or superficial deposit type. The maps are digitized with a view to presentation at a scale of 1:1 000 000 (overview map).
