In order to reassess the geomorphologic development of the Rangsdorf lake area a strategy combining the technical potentials of a GIS with geomorphologic fieldwork was developed.

The main focus was on updating the Prussian Geological Maps from the 19th century. https://macorners.shop/product-category/gift-box-set/
