Map based index (GeoIndex) site investigation reports

[This metadata record has been superseded, see http://data.bgs.ac.uk/id/dataHolding/13480403]. This layer of the map based index (GeoIndex) shows the location of site reports covering a wide range of drilling and site investigation work. Some 2000 reports include the logs from over 10 000 boreholes in addition to those held in the borehole index. The rectangles shown are drawn using the SW and NE corners of the site maps.
