| summary: | The Digital Geological Model (DGM) is a regional-scale layer model of the subsurface of the Netherlands to a depth of 500 metres. The geological layers in this depth interval consist mainly of unconsolidated sediments such as clay, sand and gravel. They have been classified into lithostratigraphic units on the basis of their lithology and other rock properties. The DGM provides insight into the stacking and spatial relationships of these lithostratigraphic units. In this model the base and top of the units are displayed by depth maps. The thickness of the units is derived from the grid maps of the surface and the base. The DGM covers onshore Netherlands only and therefore the subsurface of the Dutch part of the North Sea is not included. |
