In the Netherlands subsurface data is legally arranged via The Basis Registratie Ondergrond, aka BRO: https://www.broinfo.nl.
TNO manages this data, and serves it via EU INSPIRE compliant web services via:
https://www.broinspireservices.nl/arcgis/rest/
The OGC WMS feeds can be used to ingest data into professional; GIS packages like QGIS and ArcGIS, or load the WMS in Google Earth.
There are four subsurface models as explained on https://www.dinoloket.nl/en/explanation-subsurface-models. Each has its own WMS servie, which bundle many individual WMS layers:
- REGIS: https://www.broinspireservices.nl/arcgis/services/inspire/inspire_regis_rd/MapServer/WMSServer?request=GetCapabilities&service=WMS
- GetTOP: https://www.broinspireservices.nl/arcgis/services/inspire/inspire_geotop_rd/MapServer/WMSServer?request=GetCapabilities&service=WMS
- The explanation of the layer/formation codes can be found here https://www.dinoloket.nl/nomenclator and in this Dutch report TNO 2012 R10991.
- bcc = basis of layer, tcc = top of layer, dcc = thickness of layer, breuk = interface.
