Engineer's Geological Map 2015
The basis for the combined map is the Engineer’s Geological Map Series of Berlin, 1 : 5,000, with a total of 71 single sheets to date, which were drafted between 1993 and 2015.
In order to process the single maps, the descriptions of strata from approx. 73,000 bore holes in the geological database of the Berlin State Geological Survey were evaluated.
The basis for the ascertainment of the physical key values of the subsoil were extensive examinations over the past forty years.
