The Geological Survey Working Group of the Senate Department for the Environment, Transport and Climate Protection has drafted an Engineer’s Geological Map Series of Berlin which is, first, an important aid for construction and project planning, and secondly makes possible guiding statements on environmentally relevant issues on soil conditions of the subsoil and on foundation-relevant facts.
The digital production of the basic mapping "Engineer’s Geological Map of Berlin, 1:5,000" was initiated in 1993. It is developed in sheet lines of the official "Map of Berlin 1: 5,000". As of December 2015, it is electronically accessible in 71 single sheets. For 58 sheets exist particular maps.
The maps available to date cover all or most of the boroughs of Pankow, Marzahn-Hellersdorf, Lichtenberg, Friedrichshain-Kreuzberg, Mitte, Neukölln and Treptow-Köpenick. Currently, only some parts of the boroughs of Reinickendorf, Spandau, Tempelhof-Schöneberg and Steglitz-Zehlendorf are covered.
The geological structure of loose rock is described in detail stratigraphically (the time sequence), petrographically (the composition of the rock) and genetically (the development), as well as with physical soil key values to a depth of 10 m.
To make digital application possible even for more large-scale tasks, and to make the map available via the Internet to a broad audience, the existing single sheets have been joined together for a combined map without sheet lines.
