Topographic data and how to acquire it

The National Land Survey collects topographic data from the entire country. Our datasets contain, for example, place names, roads, buildings, waterways, fields, topographic features and elevations as well as administrative boundaries.

The road network and geographic names are updated continuously, the administrative borders and the buildings yearly and the other elements approximately every 5–10 years.

Our topographic data is available as themes and as products containing all topographic data. Product descriptions contain additional information about different topographic data products.

All of our topographic data is open data. It may be freely copied, distributed and published. It may be processed and utilised for commercial purposes and used as part of applications or services.
