The WMS D-AERO (INSPIRE) comprises airborne geophysical surveys for mapping the shallow subsurface in Germany. Since the eighties BGR carries out helicopter borne measurements in Germany as well as in neighbouring and distant countries. In particular a series of continuous areas on the German North Sea coast are flown during the last years within the context of the D-AERO project. The helicopter of type Sikorsky S-76B is operated for the airborne geophysical survey of the earth's subsurface. Usually airborne electromagnetic, magnetic and radiometric measurements are carried out. According to the Data Specification on Geology (D2.8.II.4_v3.0, sub-theme Geophysics) the information with respect to the airborne geophysical surveys is INSPIRE-compliant. The WMS D-AERO (INSPIRE) contains for each airborne geophysical survey one layer, e.g. GE.flightLine.G081Cuxhaven. The flightlines are displayed correspondingly to the INSPIRE portrayal rules. Via the getFeatureInfo request, the user obtains the content of the INSPIRE attributes platformType und profileType. Additionally, the WMS contains a campaign layer (GE.airborneGeophysicalSurvey) with the INSPIRE attributes campaignType and surveyType.

The 13 GML files for each airborne geophysical survey area together with a Readme.txt file are provided in ZIP format (D-AERO-INSPIRE.zip). The Readme.text file (German/English) contains detailed information on the GML files content. Data transformation was proceeded by using the INSPIRE Solution Pack for FME according to the INSPIRE requirements of data specification Geology (D2.8.II.4_v3.0), Sub-theme Geophysics.

BGR conducted within the EU Interreg-IIIb project "Ancient groundwater reservoirs in buried valleys" (BurVal) an airborne survey in the region of the Ellerbeker Rinne in cooperation with the State Geological Surveys of Schleswig-Holstein (LANU) and Hamburg (BSU). The survey area Ellerbeker Rinne (2005/06) is located to the northwest of the Hanseatic City of Hamburg and is about bounded by the motorway A23 to the west and by Bad Bramstedt to the northeast. The size of the area is about 280 km². The area was surveyed with 7 flights totalling to 908 line-km (235,597 survey points). The nominal separation of the 99 ENE-WSW lines and 6 NNW-SSE tie lines was 400/600 m and 2000 m, respectively. The maps display the geophysical parameters apparent resistivity and centroid depth derived from the HEM data at the five frequencies of the HEM system (0.4 - 130 kHz). Furthermore, horizontal and vertical slices were derived from layered-earth models (resistivities and thicknesses of five model layers).

BGR conducted within the project „Pilot study for a detailled airborne geophysical mapping“ (DAGLA) an airborne survey near the city of Bremerhaven. The survey area Bremerhaven (2001) is bounded by the settlements Dorum and Neuenwalde to the north, Bederkesa and Wehdel to the east, Lunestedt and Stotel to the south, and by the river Weser and the North Sea to the west. The size of the area is about 550 km². The area was surveyed with 13 flights totalling to 2227 line-km (588,067 survey points). The nominal separation of the 107 ESE-WNW lines and 26 NNE-SSW tie lines was 250 m and 1000 m, respectively. The maps display the geophysical parameters apparent resistivity and centroid depth derived from the HEM data at the five frequencies of the HEM system (0.4 - 190 kHz). Furthermore, horizontal and vertical slices were derived from layered-earth models (resistivities and thicknesses of five model layers).

BGR conducted an airborne survey in the region of the Stassfurt-Egeln salt anticline as part of a BMBF research project "Dynamic processes in flooded or abandoned salt mines and their overburden”. The survey area Stassfurt (2007) is bounded by the towns and settlements Aschersleben, Kroppenstedt, Hadmersleben, Altenweddingen, Atzendorf, Förderstedt and Bernburg. The size of the area is about 467 km². The area was surveyed with 29 flights totalling 5137 line-km (1,344,787 survey points). The nominal separation of the 197 SE-NW lines and 39 NE-SW tie lines was 100 m and 1000 m, respectively. The maps display the geophysical parameters apparent resistivity and centroid depth derived from the HEM data at the six frequencies of the HEM system (0.4 - 133 kHz). Furthermore, horizontal and vertical slices were derived from layered-earth models (resistivities and thicknesses of four model layers).

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) measuring system consists of circular (diameter about 0,5 m) transmitter and receiver coils (horizontal separation about 8 m) housed by a flying tube (bird) about 40 m beneath the helicopter. 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 at each of the six system frequencies ranging from 0.4 to 130 kHz. Furthermore, vertical and horizontal resistivity (= inverse of conductivity) sections are derived from multi-layer inversion results (1D resistivity-depth models).

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. Horizontal resistivity (= inverse of conductivity) sections are derived at several depths from multi-layer inversion results (1D resistivity-depth models).
