On 22 December 2021, the Geological Survey of the Netherlands released its new geological map of the Netherlands on DINOloket. In this portal, the map can be viewed interactively and downloaded for use in a GIS environment. A printed version, including inset maps of Aruba, Curaçao, Sint Maarten and the Caribbean Netherlands, will be published in mid-2022.
The geological map of the Netherlands shows the deposits that make up the upper metres of the subsurface. The map covers both the onshore Netherlands and the Dutch part of the North Sea. Map units represent (combinations of) formations, members and layers. For the coastal zone, Holocene sequences are portrayed. These successions of units are defined as profile types, mapped separately and identified by codes in lower-case letters to set them apart from singular units.
The geological map on DINOloket
You can view and query the map interactively on the portal. For easy orientation, you can increase its transparency and thus make the topography layer visible. You can also click on map units, which opens explanatory popups with an option to link to the Stratigraphic Nomenclator for further information. Using the legend, you can search for and highlight specific map units. Importantly, it is possible to download the GIS files of the map for use in your own GIS project environment.
The geological map on paper and as PDF
The map is currently being prepared for high-quality printing on paper. As soon as the printed map is published, a digital version will be made available in PDF format on DINOloket. You can pre-register here for a paper copy. In addition to the main map, the print and PDF file will contain an extensive legend as well as cross-sections through the deep subsurface.
Aruba, Curaçao, Sint Maarten and the Caribbean Netherlands
The paper map and PDF show the entire Kingdom and include new geological maps of Aruba, Curaçao, Sint Maarten and the islands of the Dutch Caribbean: Bonaire, Sint Eustatius and Saba. The Caribbean island geology is not shown interactively on DINOloket, but can be downloaded there as GIS files.
