Hydrogeological Map of Germany 1:250,000 (HÜK250) (WMS)

In order to support the implementation of the European Water Framework Directive (EU-WFD), the German State Geological Surveys (SGD) and the Federal Institute for Geosciences and Natural Resources (BGR) agreed in 2000 to compile a digital hydrogeological map at the scale of 1:200,000 (HÜK200), providing a harmonised survey of the upper groundwater bodies in Germany. The HÜK200 captures hydrogeologically relevant attributes such as consolidation, type of porosity, permeability, type of rock and geochemical classification to describe the hydrogeological characteristics of the rocks of the uppermost aquifers. The geological information on lithology, stratigraphy and genesis of the geological map of Germany 1:200,000 (GÜK200) provided the basic data. This information was evaluated and hydrogeologically interpreted by regional experts of the SGD or replaced and completed by other regional geological and hydrogeological maps and data where necessary. 2019, HÜK200 was migrated to a scale of 1:250.000 (now HÜK250).
