The map of the plant available water in Germany gives an overview of the amount of water which is available for plant growth in the summer period (April – September). It is the sum of the available water holding capacity of soils the precipitation in summer and the amount of capillary rise. The map was made on the basis of the land use stratified soil map of Germany at a scale of 1:1,1000,000, climate data for the period of 1961–1990 and land use information is derived from the Corine Land Cover data set (2006). The method is part of the TUB_BGR approach to model seepage water and is published in the documentation of Ad-hoc-AG Boden (representing the soil experts of the geological services of the German federal states).
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).
Based on radar data recorded by the European ERS-1/ERS-2 satellites between 1992 and 2001, annual ground motion rates for Berlin and Hanover were derived through utilization of the technique of Persistent Scatterer Interferometry (PSI). In these data, areas of ground motion were identified and assigned to PanGeo Polygons, which were geologically interpreted.
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 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.
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).
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).
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 visualisation of the protection potential of aquifer covering strata is a contribution of the State Geological Surveys (SGD) to describe the groundwater bodies as part of the reporting commitment for implementing the European Water Framework Directive. The indicated protection potential refers to the upper contiguous aquifer based on the specifications of the LAWA working guideline and suggests a categorisation of good, medium or poor protection potential. Depending on the availability of adequate digital information to assess the protection potential, two approaches have been established by the federal states. Approach 1: Using conventional empirical methods, the states of Berlin, Brandenburg, Hesse, Mecklenburg-Vorpommern, Lower Saxony, North Rhine-Westphalia, Rhineland-Palatinate, Saarland, Saxony and Schleswig-Holstein have classified existing spatial information (from HÜK 200 or other state-specific basic information) and / or point information (profiles of boreholes) regarding their potential protective effect towards the intrusion of contaminants and have interpreted these according to LAWA guidelines. Approach 2: In the states of Baden-Württemberg, Bavaria, Hamburg, Saxony-Anhalt and Thuringia a methodology – developed by the SGD´s – for the determination of the protection potential of aquifer covering strata (HÖLTING et al., Geol. Jb. C 63, Hannover 1995) was applied. It concludes in more differentiated statements, however, it requires comprehensive information on percolation rate / groundwater recharge, available field capacity of the soil, rock type and thickness of the aquifer covering strata, the structural properties of the hard rocks and artesian conditions. The classification is based on a scoring system and was translated according to LAWA standards. Areas of stagnant surface water and areas with insufficient information density have not been rated.
The map shows the representative chemical content of groundwater for 22 hydrogeological subregions of Germany. The classification of each sub-region was based on the TDS value (total dissolved solids) and the chemical inventory. According to the degree of mineralization, five classes of waters were distinguished (very small, low, medium, high and strongly changing solution contents). The classification of the waters by their chemical inventory was made according to the equivalent percentage of the main cations and anions based on the Piper quadruple diagram. With this chemical classification and the degree of mineralization, 22 geogenic groundwater types could be differentiated throughout Germany. The basis for the mapping of geogenic groundwater quality is the "Hydrogeological Regions" map. The water quality data comes from the groundwater monitoring networks of the German federal states, which were collected by the State Geological Surveys or the State Environmental Surveys. Further analyses are based on the data of the former Central Geological Institute (ZGI) of the GDR. In total, sample data of nearly 8,000 observation wells have been evaluated.
