At the Danish Geodata Agency, we collect, quality assure and distribute authoritative property and hydrographic data. We work across a variety of authorities and stakeholders for the benefit of society as a whole.
We produce and compile geospatial data about the sea. We make data, nautical charts and other maritime products for Danish and Greenlandic waters available to allow for safe navigation and public administration at sea.
We monitor more than 520,000 km of cadastral boundaries which define every property in Denmark.
With around 65,000 annual passages, Danish waters are among the busiest in the world. And with a Greenland coastline, which is longer than the circumference of the earth , it remains crucial to perform hydrographic surveys and produce charts of the Danish and Greenlandic waters. Denmark remains one of the world’s leading maritime nations, and it is through our efforts that ships can navigate safely through the waters of Denmark and Greenland.
Our work is based on a long history of proud traditions. We have surveyed land and sea for more than two centuries. The Royal Danish Nautical Charts Archive was founded in 1784. In 1844, the Danish Cadastre was established to provide the basis for fair taxation of land, and since then, we have continued to update the cadastre with data on all properties in Denmark. Our fundamental responsibilities have remained unchanged to this day; we still keep track of the details and characteristics of the land and sea. The difference is that we have gone from working with measuring tapes and lead lines to using multibeam echosounders, satellites and digital data processing.
