The map of the relative binding strength of isoproturon in topsoils (0-30 cm) gives an overview of the sorption of this pesticide in the soils of Germany. A high binding strength of isoproturon can reduce the harmful impact on the environment by a decreased mobility. The decomposition of isoproturon in soils was not taken into account during generation of the map. The basis for calculation of the binding strength was the soil map 1:1,000,000 (BUEK1000) as well as linking rules and tabular values of isoproturon binding from Mueller & Waldeck (2011) and Rexilius & Blume (2004). However, the rank of isoproturon binding by clay was recalculated based 175 datasets of 18 publications (shift from rank 5 to rank 1). The binding strength of isoproturon depends on the content of organic matter and the soil texture (proxy for the content of clay minerals and sesquioxides) in this evaluation.

The map shows spatial units of Germany that can be uniformly described and delimited with respect to the type of flow as well as the chemical composition of the groundwater. In total, a distinction is made between five regions and 24 subregions, which have been assigned to the most important landscape units in Germany. For each subregion, a schematic lithological column profile has been compiled, showing a typical layered structure of the subsurface of each region. The types of rock are additionally subdivided into aquifers, aquitards and aquicludes. The aquifers are classified into the three classes of pore, fractured and karst aquifers, while the aquitards are divided into unconsolidated or consolidated rocks. Another distinction is made according to the prevailing chemical environment of the rock (silicate, carbonate, sulphate, organic). As a result, ten types of aquifers and six types of aquitards are distinguished. The basis for the map is the digital data of the Geological Map of Germany 1:1,000,000 (GK1000).

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 passive radiometric (HRD) system is installed into the helicopter and consists of a gamma-ray spectrometer with five Sodiumiodid detectors to measure the gamma radiation. The results are as maps displaying total count, exposure rate as well as (equivalent) concentrations of Potassium, Thorium and Uranium at ground level.

Web Map Service (WMS) of the map Groups of soil parent material in Germany 1:5,000,000. The presented map at scale 1:5,000,000 shows the distribution of 15 soil parent material groups in Germany with polygons of at least 64 square kilometers. Parent material is the rock, from which soil is formed. It was derived from the landuse use stratified soil map of Germany at scale 1:1,000,000. The version 3.0 of the map is based on the Digital Landscape Model 1:1,000,000 (DLM1000) of the Federal Agency for Cartography and Geodesy.

Soils can be classified according to important and typical soil characteristics. Such a fundamental property is the composition of the soil or soil type. The soil type describes the size of the mineral particles from which a soil is built. The content of organic matter in the upper soil determines how much water or how much nutrients can be stored in the soil. The soil thickness describes the space under the earth's surface that can be rooted by plants. The theme maps of soil characteristics in Germany are based on the landuse stratified soil map of Germany 1:1,000,000 (BUEK1000N), more than 9000 quality-assured soil profiles of the federal states from a twenty-year period and on the land use dataset CORINE Landcover 2006 (UBA).

Web Map Service (WMS) of the BUK5000. 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 map “Groundwater resources in the ECOWAS region” captures and standardises existing groundwater data of West Africa and gives a consistent regional overview on the groundwater resources. It provides a quantitative assessment of aquifer productivity using a combination of aquifer flow type and expected borehole yield. The map highlights the suitability of aquifers for water supply on different scales while at the same time showing the physical limits of groundwater development. Map elaboration comprised the harmonisation of existing continental and regional geological maps and the attribution of hydrogeological units with expected yield data compiled from a literature metasurvey. Insert maps highlight the geological structure, geogenic background levels of arsenic and fluoride, and groundwater recharge.

The map series General Geological Map of the Federal Republic of Germany 1:200,000 (GÜK200) is the result of cooperation between the State Geological Surveys of the Federal Republic of Germany (SGD), the Geological Surveys of neighbouring countries and the Federal Institute for Geosciences and Natural Resources (BGR). The GÜK200 displays the surface geology of Germany and adjacent areas of neighbouring countries on 55 map sheets. The map sheets show the regional dissemination of more than 3800 geological units. The geological units contain information on stratigraphy (age), genesis and petrography (composition) of the rocks.

Web Map Service (WMS) of the BUEK3000. The BUEK3000 is prepared by the Federal Institute for Geosciences and Natural Resources (BGR) for the National Atlas of Germany. Based on the generalized and aggregated soil map 1:2,000,000, it shows 43 mapping units with information about soil texture, parent material, dominant and associated soils.

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).
