About the Danish Geodata Agency

We ensure that geospatial data about the sea and real property is easily accessible and reliable.

Land and sea
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 register changes in basic data about properties and owners. We make data available as a legal basis for transactions, mortgaging and taxation of property in Denmark. The data is also used as basic data for other public administration.

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 keep track of the fundamentals
We monitor more than 520,000 km of cadastral boundaries which define every property in Denmark. This provides a crucial foundation for administration of properties for owners, companies and authorities. These data are important, not least because it safeguards the property rights that are inviolable under the Constitution of Denmark (Grundloven).

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. One of its responsibilities was to create nautical charts that allowed ships to navigate safely through the waters of the Kingdom of Denmark.

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.

Even though our responsibilities have not changed in a significant way, technology and the needs of society are evolving constantly. Accordingly, we employ innovative solutions and continually adopt new and more accurate methods, technologies and tools. We believe this is a prerequisite to providing current, easily accessible and high-quality data for the benefit of everyone. We are proud of being specialists and attach great importance to expertise.

The growth of digitisation requires more coherent public data and services. We are therefore developing our data and processes to ensure they can create value in common public and private sector solutions. That is also why we provide coherent marine data for all of Denmark.

Dialogue and cooperation
Our goal is to be an attractive partner that creates value for society through dialogue and cooperation with authorities, companies and individuals. We offer our expertise because we believe it makes a difference and because we wish to support the development of society.
