Mapping buried Holocene landscapes: past lowland environments, palaeoDEMs and preservation in GIS

In a geological GIS-data recombination project, a digital map was produced that holds information on the Netherlands’ former coastal and delta plain landscapes in the last 14,000 years: the Holocene and the very end of the Pleistocene. The end product polygon maps are accompanied by a set of palaeoDEMs indicating the ‘attention depth’ for buried land surfaces and aquatic deposits; both for four time slices. This paper provides conceptual background on legend and construction principles of the polygon maps and the palaeoDEMs (‘decisions during the making off’) and a basic overview of the map pr...
