Raw Data on Helicopter-borne Magnetics (HMG) Area 109 Hadelner Marsch

BGR conducted an airborne survey in the region of the Hadelner Marsch in cooperation with the GGA Institute (now LIAG) as well as with the water suppliers of Land Hadeln and Wingst. The survey area Hadelner Marsch (2004) is bounded by the river Elbe to the north and by the settlements Bederkesa and Lamstedt to the south. The size of the area is about 700 km². The area was surveyed with 20 flights totalling to 2973 line-km (757,050 survey points). The nominal separation of the 117 ESE-WNW lines and 13 NNE-SSW tie lines was 250 m and 2000 m, respectively. The ASCII datafile contains the raw data as well as the processed HMG data.BGR与GGA研究所（现更名为LIAG）以及哈德尔恩郡与温斯特的供水企业合作，在哈德尔沼泽（Hadelner Marsch）区域开展航空勘测。本次勘测的区域为2004年作业的哈德尔沼泽，其北界为易北河，南界为贝德克萨（Bederkesa）与拉姆施泰特（Lamstedt）居民点，总面积约700平方千米。本次勘测共实施20架次飞行，总测线长度达2973千米，共获取757050个勘测测点。其中117条东东南-西西北（ESE-WNW）主测线与13条北东北-南西南（NNE-SSW）联络测线的标称间距分别为250米与2000米。本ASCII格式数据文件包含原始勘测数据与经处理的HMG数据。
