Raw data of helicopter electromagnetics (HEM) area 109 Hadelner March

The BGR carried out an extensive flight in the Hadelner March area in cooperation with the GGA Institute (today LIAG) as well as the water supply associations Land Hadeln and Wingst. The measuring area Hadelner Marsch (2004) is bounded by the Elbe in the north and by the villages Bederkesa and Lamstedt in the south. The area size is about 700 km² and 20 measuring flights with a total profile length of 3 019 km (771.397 measuring points) were needed to cover the entire measuring area. The Sollab level of the 117 OSO-WNW measurement profiles is 250 m, the Sollab level of the 13 NNO SSW control profiles is 2 000 m. The two ASCII data files contain the raw data as well as the processed HEM data at five measuring frequencies (0.4-140 kHz).
