  • The map of the air capacity of soils in Germany gives an overview of the content of air in a soil at field capacity. The map shows the air, which is available for plant growth from the surface to effective rooting depth, which is derived from land use and soli data. The method is published in the Bodenkundliche Kartieranleitung 4 (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).

  • This dataset has been compiled within the BGR project "D-AERO-Auswertung" based on several survey area located along the German North Sea coast. The BGR helicopter (Sikorsky S-76B) is used for airborne geophysical surveying of the Earth’s subsurface. The standard equipment comprises the methods electromagnetics, magnetics and radiometrics. The active multi-frequency, helicopter-borne electromagnetic (HEM) system, which consists of circular (diameter about 0.5 m) transmitter and receiver coils (horizontal separation about 8 m) operating at five and since 2007 at six system frequencies, is housed by a flying tube (bird) about 40 m beneath the helicopter. The HEM system used before 2002 consisted of rectangular coils (horizontal separation slightly less than 7 m) and five system frequencies (0.4 - 190 kHz). The ratio of received and transmitted signal yields to the electrical conductivity down to 50/150 m depth in case of conductive/resistive subsurface. The results are displayed as apparent resistivity (= half-space resistivity) and centroid depth maps at each of the six system frequencies ranging from 0.4 to 130 kHz.

  • The map of the groundwater influence on soils in Germany gives an overview of depth of groundwater below the surface. Soils that are influenced by groundwater usually have a limited crop yield. The map shows the classified depth of the groundwater. The ground water level is derived from profile data of the landuse stratified soil map of Germany at scale 1:1,000,000. The method is published in the Bodenkundliche Kartieranleitung 5 (2005) 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 map of the annual rate of capillary rise from the groundwater zone into the effective rooting zone of the soils in Germany gives an overview of the amount of groundwater that passes through evapotranspiration to the surface.

  • The map of the direct runoff on agricultural soils gives an overview of the average annual amount of precipitation, which does not infiltrate into the soils. It is based on pedological, relief and climatic factors. The map was created by using the empirical SCS – runoff curve number approach. The method was adapted by the Federal Institute for Geosciences and Natural Resources (BGR) as part of the attempt to model the seepage volume in the TUB_BGR method. The land use stratified soil map of Germany at scale 1:1,000,000 was used as pedological input to the model. The relief data was derived from the DEM50 of the BKG. The mean annual precipitation data of the period 1961 -1990 (DWD) is used as an input as well. The land use information is derived from CORINE Land Cover data set (2006).

  • WMS Service of the 'Map of Mining and Storage Operations of the Federal Republic of Germany' (BergSP). The 'Map of Mining and Storage Operations of the Federal Republic of Germany' on a scale of 1:2,000,000 is published by the Bundesanstalt für Geowissenschaften und Rohstoffe (Federal Institute for Geosciences and Natural Resources) in cooperation with the mining authorities of the federal states. It shows the locations of mining operations for coal, lignite, petroleum, natural gas, raw material, iron and manganese ore and salt. The annual deliveries are presented in six categories. The storage operations for petroleum, natural gas, compressed air and waste disposal sites are distinguished by their type. Moreover, the map contains the locations of geothermal plants.

  • The spatial distribution of geogenic groundwater background values for hydrogeochemical and physicochemical parameters of the near-surface groundwater bodies is represented based on the HÜK200. Background values are used to describe the nature of the groundwater bodies and provide a basis for decisions on the differentiation between geogenic and conspicuous data. The representation of background values is a contribution of SGD and BGR to describe groundwater bodies and thus serves to implement the European Water Framework Directive (WFD).

  • The IHME1500 v1.2 is a vector dataset resulting from the digitisation of the 25 published map sheets of the International Hydrogeological Map of Europe at the of scale 1:1,500,000 (IHME1500). The dataset was extended for five unpublished, digitised IHME1500 map sheets to achieve full map coverage. It consists of selected features of the IHME1500 with the following content: - Aquifer types (area): Distinction of six types of aquifers according to their productivity and void types. - Lithology (area): Lithological classification of the aquifers at five aggregation levels. - Seawater intrusion (area): Areas with salination of groundwater caused by sea water intrusion. - Tectonic fractures (line): Geological lineaments assigned to the five classes of known or supposed faults or overthrusts and boundaries of fractured belts in Iceland. The IHME1500 v1.2 includes a correction of inconsistencies of the printed map sheets and was spatially adjusted to an up-to-date topographic base. The IHME1500 is a hydrogeological map series consisting of 25 published map sheets with explanatory notes that covers the European continent and parts of the Near East. The Federal Institute for Geosciences and Natural Resources (BGR) and the United Nations Educational, Scientific and Cultural Organization (UNESCO) are the project coordinators, supported by the International Association of Hydrogeologists (IAH) and the Commission for the Geological Map of the World (CGMW). Each sheet consists of contributions by the respective countries represented in the map, which were harmonised across borders. The map series including the explanatory notes can be used for scientific purposes, for large-scale regional planning and as a framework for detailed hydrogeological mapping.

  • Web Map Service (WMS) of the map Heavy metal and trace element background values in German Soils. A concept to derive spatially representative heavy metal and trace element background values in topsoils, subsoils, and deeper soil horizons was developed and applied. The concept is based on a differentiation of background values according to soil parent material groups at the first level. Spatial information is given by a small-scale (1:1,000,000) digital map of soil parent material groups and additional information on soil types. For top soils the background values are also differentiated according to land use. To derive representative background values site-specific soil data have been compiled from different sources (soil data from federal institutions and institutions of the federal states) regarding aspects of data harmonization and minimum soil information requirements. Based on information of about 5000 soil profiles representative background values for top soils, sub-soils and deeper soil horizons can be derived for the dominating groups of soil parent material in Germany with a current spatial coverage of about 90%. More information about the method is given in the LABO-report (2003): 'Hintergrundwerte für anorganische und organische Stoffe in Böden, 3. überarbeitete und ergänzte Auflage'.

  • For farming, the production function of the soils and thus the natural soil fertility play a decisive role. A healthy soil with its properties, potentials and functions is the basis for high land yields, but at the same time also the basis for sustainable agriculture and responsible land use. The theme maps of soil capability in Germany are based on the landuse stratified soil map of Germany 1:1,000,000 (BUEK1000N), the Digital Elevation Model DGM50 of the German Federal Agency for Cartography and Geodesy (BKG), climatic information of the German Meteorological Service (DWD) for the period 1961-1990 as well as on land use data from the data set CORINE Landcover 2006 (UBA).
