  • The General Geological Map of the Federal Republic of Germany 1:250,000 (GÜK250) is a seamless “Inselkarte” and the digital follower of the General Geological Map of the Federal Republic of Germany 1:200,000 (GÜK200). Like its predecessor, the GÜK250 represents the surface geology of Germany and contains harmonised and updated information on age, composition and genesis of the rocks. According to this content, the GÜK250 offers three nationwide legends for the portrayal of the geologic units: a) chronostratigraphy, b) petrography and c) petrogenesis. Furthermore, the new GÜK250 includes information on the lithostratigraphy, the genetic process as well as information on the physical and chemical environment of the rock formation. Additionally, the GÜK250 provides - if available - information on the thickness of the geologic units and contains layers which represent tectonic elements, marginal position of the ice shield and quartz dykes. In general, the term “surface geology” refers to geologic formations up to a depth of two meters. However, particularly in the south of Germany, considerable deviations of this concept exist and thicknesses of a couple of hundred meters may are displayed. The GÜK250 contains a base layer and an overlay layer which usually comprises thin Quaternary deposits.

  • The BUEK5000 is derived form the landuse stratified soil map of Germany at scale 1:1,000,000 by aggregation, focused on information about the parent material, and generalization. The maps shows 20 soil (23) legend units with polygons of at least 64 square kilometers.

  • The German Earthquake Catalogue is based on a database providing information on the seismicity in Germany an adjacent areas. It contains locations of seismic events since year 800 where their epicentre determinations are based on historical sources as well as on measurements at seismometer stations since the start of instrumental seismological recording in the 20th century. Today, digital data acquisition at seismometer stations of the German regional seismic network (GRSN), the seismic GERES array, and the Gräfenberg array (GRF) takes place. All events with a local magnitude ML 2.0 and higher are listed. The GML file together with a Readme.txt file are provided in ZIP format (GERSEIS-INSPIRE.zip). The Readme.text file (German/English) contains detailed information on the GML file content. Data transformation was proceeded by using the INSPIRE Solution Pack for FME according to the INSPIRE requirements. Due to the continuous processing of the seismic events, the INSPIRE dataset is updated annually.

  • The map of the field capacity of soils in Germany gives an overview of the amount of water which can be stored in a soil (depth 1 m). The water storage capacity is a key function of soils. The field capacity was derived from the landuse stratified soil map of Germany at scale 1:1,000,000. The method is published in the Bodenkundliche Kartieranleitung KA4 (1994) and in the documentation of Ad-hoc-AG Boden (representing the soil experts of the geological services of the German federal states). The land use information is derived from the CORINE Land Cover data set (2006).

  • The Potential Wind Erosion Risk map gives an overview of the exposure of arable soils to soil loss due to deflation in Germany. It is based on pedological and climatic factors. The method to predict the soil erosion risk is published in the DIN 19706:2002 and in the documentation of Ad-hoc-AG Boden (representing the soil experts of the geological services of the German federal states). For the application with soil maps, the method was adapted by the Federal Institute for Geosciences and Natural Resources (BGR).The land use stratified soil map of Germany at scale 1:1,000,000 was used as pedological input to the model. The mean annual wind speed at 10 meters above ground level of the period 1980-2000 (DWD) is used as well. The land use information is derived from CORINE land cover data set (2006).

  • The application “Information System Salt Structures” provides information about the areal distribution of salt structures (stocks and pillows) in Northern Germany. With general structural describing information, such as depth, secondary thickness, types of use or state of exploration, queries can be conducted. Contours of the salt structures can be displayed at horizontal cross-sections at four different depths up to a maximum depth of 2000 m below NN. A data sheet with information and further reading is provided for every single salt structure. Taking into account the fact that this work was undertaken at a scale for providing an overview and not for investigation of single structures, the scale of display is limited to a minimum of 1:300.000. This web application is the product of a BMWi-funded research project “InSpEE” running from the year 2012 to 2015. The acronym stands for Information system salt structures: planning basis, selection criteria and estimation of the potential for the construction of salt caverns for the storage of renewable energies (hydrogen and compressed air)”.

  • Since the eighties BGR carries out helicopter borne measurements in Germany as well as in neighbouring and distant countries. In particular a series of continuous areas on the German North Sea coast are flown during the last years within the context of the D-AERO project. The helicopter of type Sikorsky S-76B is operated for the airborne geophysical survey of the earth's subsurface. Usually airborne electromagnetic, magnetic and radiometric measurements are carried out. The 13 GML files for each airborne geophysical survey area together with a Readme.txt file are provided in ZIP format (D-AERO-INSPIRE.zip). The Readme.text file (German/English) contains detailed information on the GML files content. Data transformation was proceeded by using the INSPIRE Solution Pack for FME according to the INSPIRE requirements of data specification Geology (D2.8.II.4_v3.0), Sub-theme Geophysics.

  • The GK1000 (INSPIRE) represents the surface geology of Germany and adjacent areas on a scale of 1:1,000,000. According to the Data Specification on Geology (D2.8.II.4_v3.0) the content of the geological map is stored in three INSPIRE-compliant GML files: GK1000_GeologicUnit.gml contains the geologic units, GK1000_GeologicStructure.gml comprises the faults and GK1000_NaturalGeomorphologicFeature.gml represents the marginal position of the ice shield. The GML files together with a Readme.txt file are provided in ZIP format (GK1000-INSPIRE.zip). The Readme.text file (German/English) contains detailed information on the GML files content. Data transformation was proceeded by using the INSPIRE Solution Pack for FME according to the INSPIRE requirements.

  • The Hydrogeological Map of Germany (HÜK200) describes the hydrogeological characteristics of the upper contiguous aquifers in Germany at a scale of 1:200,000. Included are five hydrogeological attributes that are shown in the following thematic maps: - Solidification - Rock type - Aquifer type - Permeability - Geochemical rock type. The classifications are based on the guidelines for the compilation of hydrogeological maps, published in 1997 by the State Geological Surveys (SGD), and were extended and revised in the context of the project. The HÜK200 is designed as a digital map series. The data is visualized in BGR’s Geoviewer and available through the product center of BGR. The HÜK200 was launched in 2000 and is a joint project of the State Geological Surveys under the auspices of BGR. Hydrogeological information, which is harmonized across all federal states, is now digitally available for all parts of Germany. This was and still is required for the implementation of the EU Water Framework Directive (WFD). In just three years, the first version of the HÜK200 was compiled. Scientific basis provided the digital Geological Map of Germany 1:200,000 GÜK200 (with information on lithology, stratigraphy and genesis), and geological and hydrogeological maps from the Federal States, which were hydrogeologically interpreted and classified using the regional expertise of SGD. Since late 2006, the advanced and extended version 2 is available, which includes a completely redesigned database and a uniform national general legend. The latest version 3 of the HÜK200 features a seamless spatial vector dataset and includes further corrections and improvements.

  • 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).
