Bro Digital Geological Model (DGM) ATOM

The Digital Geological Model (DGM) is a three-dimensional layer model of the Dutch subsurface to a depth of about 500 m below NAP, with local outliers up to 1 200 m. The subsurface layers in this part of the subsurface mainly consist of unpaved sediments, in which the soil types of clay, sand, gravel and peat occur. The layers are divided into lithostratigraphic units based on differences in lithology and other properties. DGM is a model of the structure and coherence (geometry) of these lithostratigraphic units. The height of the bottom and top and the thickness of the units are recorded in grid files (grids) with a cell size of 100 by 100 m. In addition to the layer information, DGM also contains the interpreted drilling descriptions used in making the model. The model area of DGM consists of the mainland of the Netherlands. The subsoil of the Dutch part of the Continental Plate is not included in DGM. DGM is a regional model. It is not suitable for use on a local scale; to create a local subsurface model, additional data will always be required.
