In the years that followed, several mapping programmes were executed. First, in the early 1950s, new insights into the economic value of geological knowledge enhanced the new near surface geological mapping. From 1985 to 2004, deep subsurface mapping resulted in 15 map sheets covering the entire onshore area at a scale of 1: 250,000. By 1997, TNO-Geological Survey of the Netherlands had begun producing 3D subsurface models. These works include models of the onshore area to a depth of about 5,000 m and models of the Dutch Continental Shelf.
The archive of borehole records, geological maps, geological memoirs and 3D models the Geological Survey has assembled is of great scientific and practical value. It enables the Geological Survey of the Netherlands to answer the important questions of today, and those of tomorrow.
Now that we have been active for 100 years, we’d like to share our insights with you. On 5 October 2018, we will arrange a symposium that addresses the past, present and future developments in geological mapping. On this page, we will keep you updated about the centennial celebration and other activities planned for this year. For instance, in 2018, we will distribute the fourth geological overview map of the Netherlands.
