Model: Geomorfologische kaart 1:50.000 (GMM)
The Geomorphological map of the Netherlands 1:50.000 is a nationwide digital map file that discribes and spatially represents the landforms occurring in the Netherlands. The landforms are described according to shape characteristics, relief, genesis and age.
Geomorphology is the science that studies the shapes of the Earth's surface and the processes that play or have played a role in their formation. The Geomorphological map of the Netherlands 1:50,000 describes the landforms occurring in the Netherlands. The Geomorphological Map of the Netherlands was created in the period 1960-2004. Various mapping methods were used during this period. Also, due to land use changes, the map is no longer up to date.
The aim of the update of the Geomorphological map of the Netherlands is an up-to-date and topographically correct representation of the geomorphology of the Netherlands based on current scientific knowledge with an accessible legend that matches the knowledge needs of the user.
Updating is a semi-automatic process of digitizing landforms based on a digital terrain model (AHN) and machine learning (ML). The auxiliary information is used to interpret visible patterns in the DTM to landforms formed by active processes or geomorphological processes in the near or distant past such as: aeolian, marine, or fluvial erosion and sedimentation, glacial processes, denudation, tectonics, organogenic processes or an anthropogenic origin.
An up-to-date topographic basis (TopNL) and the BRO subsurface models GeoTOP and soil map will be used for the update.
Geomorphology focuses on updating in a new area, geared to the updating of the Soil Map and the questions that come in. In addition, a separate layer with the dikes in the geomorphological map will be updated in 2022.
