Netherlands Geological Survey makes datasets available on a European scale

View and use pan-European subsurface datasets The Geological Survey of the Netherlands (GDN), part of TNO, offers open, harmonised and standardised data sets of the Dutch subsurface via its various portals such as Dinoloket and NLOG. We are also working with other geological surveys and scientific institutes in a pan-European setting to build a Geological

Minerals Information System (DIS) now also available via DINOloket

The Minerals Information System (DIS) is a model that supports policy and decision-making to enable the sustainable development of the North Sea and its coastal area. It is a regional model that provides insight into the quantity and quality of available sand resources.

New geological map of the Kingdom of the Netherlands

The new geological map of the Kingdom of the Netherlands is available. The state of knowledge of the Dutch subsurface is summarised by the Geological Survey of the Netherlands (GDN) in an overview map that is only released once every few decades. The last geological map dates from 1975.

Zeeland and Goeree-Overflakkee updated in GeoTOP

The Geological Survey of the Netherlands (GDN) has completely updated the Zeeland and Goeree-Overflakkee area in its 3D shallow subsurface model, GeoTOP. This innovation provides valuable information for anyone dealing with issues involving the shallow subsurface in that area.

Groundwater in the Netherlands is a complex issue

We are already using a lot of drinking water in the Netherlands, and the demand for it is only increasing. Some of our drinking water comes from surface water. But another part, especially in the higher areas of our country, comes from the subsurface, the earth’s strata. With the demand for drinking water being so

New overview map

The new geological map of the Kingdom of the Netherlands is available. The new map offers a greatly improved image of the mainland, an entirely new representation of the geology of the North Sea, and for the first time includes the Caribbean part of the Kingdom.

Groundwater dating

Groundwater dating to better understand the subsurface At the Geological Survey of the Netherlands, we carry out groundwater dating. In cooperation with universities at home and abroad, we measure various stable and radioactive isotopes (also called tracers). We use them to determine the age of the groundwater, which gives us and our clients more insight

Information provision to local governments

We see an increasing need for information and knowledge about the subsurface amongst municipalities, provinces, water authorities, and environmental services. That is why we work together with various regions on issues about subsurface energy, mining, groundwater, and the link between the surface and subsurface. We also provide support in setting up a knowledge network and act as a sounding board for subsurface research.
