The cadastral system of Norway
Valstad, Tor
The subdivision act from 1980 introduced a nationwide register for properties, addresses and buildings. It was the municipalities that collected this information through the approval process from applications of subdivisions, buildings and local development plans. Although this register included central coordinates for the properties, addresses and buildings it was far from a geographic information system. There was no map included in the system and the cadastral map was a separate system even when it became digital in most municipalities in the late 1990-ies. A new law on the cadastre has been in the making for several years. The new law was passed by the Parliament in 2005, and then changed and a revised law passed in June 2007. It is still not enacted. But a few paragraphs from this law were enacted in February 2006, enabling the Norwegian Authority on Cadastre and Mapping to introduce a new cadastral register in Norway. This new cadastral register will accept converted data from the 1980 registers, but will in addition introduce a digital cadastral map as part of the system. This paper will present the new cadastral system of Norway and give details of its content and the process of introducing it to the municipalities.
