The Map of the Worldwide Distribution of Precambrian Rocks is a general map which shows Precambrian rocks, partly under Quaternary sediments. The map is based on data of the Geological Map of the World (Bouysse 2010) of the Commission of the Geological Map of the World (CGMW). It also displays rock units that contain other rocks in addition to Precambrian rocks.

With the Hanover City Railway we will go on a time travel through the geology of Hanover. Under the streets of Hanover - in German: UStraH - we travel through 170 million years of earth history between the Upper Cretaceous and the Zechstein. We will show you what awaits you on this journey with ten selected stops.

Small-scale soil maps are usually derived from large- or medium-scale soil maps by spatial generalization and content aggregation. A uniform pedoregional classification is required to ensure a comparable approach even across regions. The presented data set at the aggregation level of soil landscapes comprises the 36 most important lithogenetic units in Germany relevant to soil science and is essentially based on the Soil Map 1:200,000 (BUEK200) published jointly by the Federal Institute for Geosciences and Natural Resources (BGR) in cooperation with the National Geological Surveys (SGD) of the federal states and its soil landscape classification. Additionally included are the soils of larger settlement, industrial and commercial areas (as BGL 13.1) and the soils of post-mining landscapes (as BGL 13.2). More detailed information on the soil regions and soil landscapes of the Federal Republic of Germany can be found in the Soil Mapping Guide (KA5), chapter 6.5 starting on page 335. The digital map graphics are based on the topographic principles of the Digital Landscape Model 1:250,000 (DLM250) from 2014 of the Federal Agency for Cartography and Geodesy (BKG).

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 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).

The Land use-stratified soil map of Germany at scale 1:1,000,000 (BUEK1000N), version 2.32, presents the distribution of soils and their associations nationwide in a uniform form at the aggregation level of the lead soil associations, which were intersected with 14 generalized and adjusted land use classes from CORINE Land Cover 1990. It did not appear as an analog map like the three subextracts of cropland, grassland, and forest. The digital map graphic is supplemented by climate regions, soil regions, and soil landscapes. The legend comprises 69 soil legend units with leading and accompanying soils (and information on the soil depth, the soil types, water conditions and the parent material), arranged according to soil distribution areas, partial legends arable land, grassland and forest, each subdivided according to climatic regions. The area-related content data are composed of 76 forest reference profiles, 78 cropland reference profiles, and 56 grassland reference profiles and are stored in a relational database. An additional 54-page booklet with explanations of the BUEK1000N can be purchased at GeoCenter Touristik Medienservice GmbH in 70565 Stuttgart, Germany, if required. The digital map graphics of version 2.32 are based on the topographic map of the Digital Landscape Model 1:1,000,000 (DLM1000) of the Federal Agency for Cartography and Geodesy from 2019.

The map of the relative binding strength of copper in topsoils (0-30 cm) gives an overview of the sorption of this heavy metal in the soils of Germany. A high binding strength of copper can reduce the harmful impact on the environment by a decreased mobility. The basis for calculation of the binding strength was the soil map 1:1,000,000 (BÜK1000) as well as linking rules and tabular values of copper binding from Hennings et al. (2000). The binding strength of copper depends on the pH, the content of organic matter and the soil texture (proxy for the content of clay minerals and sesquioxides) in this evaluation. The used pH was the target pH value of the soils, which was derived from tabular values according to land use by using the data of the BUEK1000.

The effective water balance is the difference between water supply and potential evapotranspiration during the main vegetation period (May-August). The water supply consists of the precipitation during this period, the amount of water present in the soil (described by the usable field capacity in the effective rooting zone) and possibly a capillary rise. The capillary rise is the result of the ascent rate per day and the culture-dependent duration of the ascent. The rate of ascent depends essentially on the soil texture and the distance of the lower limit of the effective rooting zone to the groundwater or backwater body. The landuse stratified soil map of Germany at scale 1:1,000,000 (BUEK1000N) was used as pedological input to the model. The landuse information was derived from CORINE land cover data set (CLC2006). The climate scenario data (https://www.dwd.de/ref-ensemble) was provided by the German Meteorological Service (DWD) in a resolution of 5 x 5 km. It contains 16 bias-corrected datasets (combination of global and regional climate models), which describe the scenario RCP8.5 (RCPs Representative Concentration Pathways) assuming an additional radiation of 8,5 W/m². The nine raster datasets with a resolution of 5 x 5 km represent the mean, the 15th and 85th percentile of the effective water balance during the main vegetation period in Germany for the climate periods 1971-2000, 2031-2060 and 2071-2099.

Geological distribution of aggregates (sand and gravel) in Northern Germany, especially north of the southernmost maximum of the Scandinavian inland ice sheet (Saalian and Elsterian glaciation).

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)”.
