Overview of all boreholes in the Dutch part of the North Sea and Wadden Sea, and in the Scheldt estuary. For each borehole, measurements and descriptions of each described interval are provided through an information link. This information concerns main lithology; gravel, sand, silt and clay admixture; main and secondary colour; sediment consistency; gravel and sand median class; and gravel, sand, silt, lutum, mud, shell and organic-matter percentage.

This map application gives access to key information about drilling and objects registered in the descriptive database of geological objects. The boreholes inventory includes hydrogeological and geophysical data.

ArcGIS Server Service gives access to key information about drilling and objects registered in the descriptive database of geological objects.

This database contains key information on boreholes. The database is generated about twice a year as a layer in a GIS environment for use in the Borehole Surveys application. Individual points in the application represent boreholes and polygons indicate groups of related boreholes.

The German Borehole Locations (GBL) contains all disposable borehole data in the Federal Republic of Germany provided by the German Survey Organizations (GSO). The 16 GSO are responsible for data storage, processing and transmission of all borehole related data. In the context of a nationwide cooperation project the header information of borehole data is collected by the BGR via the exchange format BoreholeML to establish a centralized access point. This service permits an easy access to the accumulated borehole data from the participating federal states. The first two aggregated layer show the drilling density distribution in a defined raster, while the single locations only appear in greater scales. The header data is queriable from each location. The web application Borehole Map Germany makes use of this service as one major source https://boreholemap.bgr.de/
