The Tromsø Mapping Authority has a national responsibility for geographic information and plays an important role in the management of property in Norway. The institution operates the national property register, which includes the registration of real estate and shares in housing cooperatives. In addition, they offer access to in-depth data through a digital application service, which gives users the opportunity to retrieve necessary information for various purposes.
The Tromsø Mapping Authority also works with the digitization of old nautical charts, which provides historical insight into maritime data. They arrange courses and workshops to promote developer dialogue and engage the public in processes such as georeferencing of maps. Furthermore, they have a focus on socially critical map data, and actively contribute to the mapping of marshes and wetlands, which is essential for environmental management and sustainable development.
