INSPIRE: Airborne geophysical surveys for mapping the shallow subsurface in Germany (D-AERO)

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. 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.自20世纪80年代起，BGR便在德国及其周边及海外国家开展直升机航空探测作业。近年来，依托D-AERO项目，团队针对德国北海沿岸的多片连续区域完成了航空探测飞行。本次作业采用西科斯基S-76B（Sikorsky S-76B）型直升机，用于开展地下地球物理航空探测。常规探测内容涵盖航空电磁、航空磁法与航空放射性测量。每个航空地球物理探测区域对应13个GML（Geography Markup Language，地理标记语言）文件，连同Readme.txt文件一同打包为ZIP格式压缩包（D-AERO-INSPIRE.zip）。该Readme.txt文件提供德英双语版本，详细说明GML文件的具体内容。数据转换工作严格遵循地球物理学子主题的《地质数据规范》（D2.8.II.4_v3.0）中INSPIRE的相关要求，采用FME的INSPIRE Solution Pack完成。
