  • Between 1977 and 1983, the Federal Institute for Geosciences and Natural Resources (BGR) took approx. 80,000 water samples and 70,000 sediment samples from streams and rivers in several sampling campaigns on the territory of the Federal Republic of Germany at that time and examined them geochemically. In addition to the geochemical prospection of areas with potentially deposits, the aim of the investigations was also to record indications of anthropogenic environmental pollution. The results of these investigations were published in the Geochemical Atlas of the Federal Republic of Germany (Fauth et al., 1985). The data collected within the framework of the Geochemical Atlas of the Federal Republic of Germany in 1985 is a geochemical survey of the former territory of the Federal Republic of Germany which is unique in its high sampling density. All later geochemical investigations were carried out with a much lower sampling density. This valuable and irretrievable data is now being made generally available via the BGR geoportals. In addition to the digital provision of the original data material, the texts from Fauth et al. (1985) and distribution maps produced according to the method used in 1985, the data were reprocessed using modern methods. The WMS shows the distribution of the measured element concentrations and parameters in stream sediments in five different coloured point and colour shaded contour maps for each element or parameter.

  • Map service of the Recycling Atlas of the Federal Republic of Germany. The map of the metal recycling sites of the Federal Republic of Germany is published by the German Mineral Resources Agency in the Federal Institute for Geosciences and Natural Resources. It shows the locations of Metal recycling sites for the metals aluminum, lead, precious metals, iron/steel, copper, magnesium, multi-metal (sites that recycle complex metal systems), multi-metal battery (sites that recycle metals from the recovery of complex battery systems), nickel, refractory metals, zinc, tin and mercury. In addition, information such as location capacities and recycling input rates can be queried.

  • In the original version of the map (Map “Hydrogeology” of the Hydrological Atlas of Germany (HAD)), the surface rocks are first divided into four main types, with further differentiation depending on the extent and productivity. This original subdivision has been resolved applying the internationally widely used Standard Legend for Hydrogeological Maps (SLHyM) after Struckmeier & Margat (1995). This makes the map clearer and easier to read, but above all, it is comparable to other European hydrogeological country and regional maps, such as the International Hydrogeological Map of Europe (IHME1500). The productivity classes have been derived from permeability values. In addition, the surface strata are divided into 19 different types of consolidated or unconsolidated rocks and four types of covering layers. The map is based on the digital Geological Map of Germany 1:1,000,000 (GK1000) published by BGR in 1993.

  • The data set includes meta data from sedimentary samples taken within the exclusive economic zone of Germany that are affected by the Geological Data Act. Also includes information on applied laboratory methods.

  • Small-scale soil maps at scales of 1:200,000 to 1:5,000,000 are usually compiled from large- or medium-scale soil maps by summarizing the soil units depicted there. A uniform pedoregional classification is required to ensure a comparable approach across regions. The presented data set at the aggregation level of the soil landscapes covers the 36 most important soil-relevant lithogenetic units in Germany and is based on the map of the soil landscapes at a scale of 1:250,000, version 1.4, which in turn was derived from the BUEK200/BUEK250. For the map scale 1:5,000,000 the units were generalized. 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 from page 335.

  • 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.

  • Web Map Service (WMS) of the BUEK2000. The BUEK2000 Version 1.0 was compiled from the BÜK1000 map by a process of generalization. The number of soil mapping units in the legend was reduced from 72 to 60 by aggregation of those units showing similar dominamt soils into single units. The map combined with selected soil profile pictures/graphics and information about soil history, soil classification and soil mapping in Germany is one fundamental part of the Hydrological Atlas of Germany (HAD). The Version 2.0, based on the BUEK2000N, Version 2.3, was cartographically adapted to a new base map.

  • 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 the distribution of potential sluiced sand north of the East Frisian Islands. There, primarily sands of medium grain size are needed for the protection of island coasts in order to compensate for the constant coastal erosion caused by rising sea levels, storm surge events and current-induced material removal and transport. The study area is limited to an area bounded on land by the -8 m NN isobath and on sea by the southern traffic separation area ("Terschelling - German Bight"). Large-scale extraction of sluiced sand is only possible down to a depth of 3 m. For future needs, local depth extractions down to a depth of 20 m below the seabed surface may have to be included in the considerations. For the evaluation of the grain size spectrum searched for, 2 maps were prepared. The observation depth differs with regard to the evaluation for a surface sampling to a depth of 3 m and a second one for depth sampling to a depth of 20 m below the seabed. Two classes were kept, showing potential occurrences of sand in the depth ranges mentioned. If the data basis is available in high quality, the general class "sand" was specified and subdivided into "fine to medium sand".

  • This dataset contains sea-borders based on Maritime Boundaries Geodatabase from Flanders Marine Institute. It contains borderlines of the Exclusive Economic Zone (EEZ) and the 12 nautical mile limit (SMZ) of Germany and neighbouring countries of North Sea and Baltic Sea. This data is compiled and prepared for displaying background information for metadata of geological surveys, according to Geological Data Act (GeolDG).
