Drilling archive

This is a geo-referenced data collection (database) with the released geoscientific drilling and profile data from the geological layer directories. The data encryption is based on the “symbol key geology (SEP1 of 1991)” of the German State Geological Services. The data will be presented in the Hamburg drilling data portal as far as a release is available. For free machine processing in accordance with the Hamburg Transparency Act, data in the format gml is provided in a rar archive. It contains the master data of all holes. Due to their size, the layer data is divided into 7 files according to the districts of Hamburg and for data protection reasons do not contain the data of private drilling for which no release is available for publication. 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 Drilling Point Map Germany, as far as release is available. The data are not available here in the original SEP1 but in the undifferentiated BoreholeML3 format. These two services provide complex GML schemas that cannot easily be processed by standard GIS clients such as ArcMap or QGis.
