Drilling archive

This is a georeferenced data collection (database) with the released geoscientific drilling and profile data from the geological strata directories. The basis of the data encryption is the "Symbol Key Geology (SEP1 of 1991)" of the State Geological Services of Germany. If approved for publication, the data will be displayed in the Hamburg Drill Data Portal. For free machine processing in accordance with the Hamburg Transparency Act, data in the format gml is provided in a rar archive. This contains the master data of all drillings. Due to their size, the shift data are divided into 7 files according to the districts of Hamburg and do not contain the data of private drilling for which no release for publication is available for data protection reasons. The download files are updated as required. For a better understanding of the data, a file with field descriptions and key lists is also provided. The data will also be provided by the WFS services ¿WFS BoreholeML 3.0 Header¿ and ¿WFS BoreholeML 3.0¿ for the drill point map Germany, subject to release for publication. The data are not available in the original SEP1 but in the more undifferentiated BoreholeML3 format. These two services provide complex GML schemas that cannot be easily processed by standard GIS clients such as ArcMap or QGis.
