Geological maps derived from GeoTOP
GeoTOP is used as a starting point to develop specific geological maps, focused on a typical user group. Examples given are a map of the surface geology, maps showing the cumulative thickness of sand, a map showing the top of the Pleistocene and a map showing the lithological characteristics of the upper 8 meters summarised in 5 distinct classes. These maps can currently only be found on the Grondwatertools.nl website.
