Cadastral mapping in Norway in transition from municipial responsibility to central cadastre
Mjos, Leiv Bjarte & Arve Leiknes
Over the last 20 years, Norwegian municipalities and the Norwegian Cadastre and Mapping Authority have cooperated to transfer data on boundaries to a digital cadastral map (DCM) in Norway. This work commenced in the early 19800s, for several reasons. The Norwegian law on the cadastre introduced in 1980 implied that cadastral survey was obligatory in cases of land subdivision, which created a need for an overview of the properties within the municipality for the administration of the law. The 19800s also saw the development of EDB technology enabling digital cadastral mapping. As the digitalisation of boundaries started in the different municipalities and regional offices of the Norwegian Cadastre and Mapping Authority, it became clear that standardization and coordination was needed to handle the digital cadastral map in a future common administration. In 1990, the Norwegian Cadastre and Mapping Authority and The Norwegian Association of Local and Regional Authorities developed a common data model for DCM. This data model has been the foundation for the development of a digital cadastre map until the present day, with hardly any modifications. Substantial investments have been made to establish DCM, and municipalities and the Norwegian Cadastre and Mapping authority have shared the costs. By May 2006, 87 per cent of the properties in Norway are registered in DCM, and approximately 80 per cent are registered with boundaries. However, the quality varies from one municipality to another, as some local authorities have put great resources into DCM with the result that they are close to having a complete cadastral map of high quality for the area, while others have paid little attention to DCM.
