Drill hole measurements

This map shows for which borehole measurements are carried out and available. These borehole measurements are supplied with the borehole in PDF format. If the drilling is available in the BGD archive, that number is also displayed. This map was first published in 2010. Subsequently, additional data were published several times. In September 2015, this layer was expanded with scans of more than 200 borehole measurements from the archive of Prof. Em. W. De Breuck.
