How we tested a complex register for Norway state management – Matrikkelen.
The cadastre, matrikkelen, is the official registry for real estate, buildings and addresses in Norway. Together with the National Registry, Det sentrale folkeregisteret, and the Entity Registry, enhetsregisteret, it constitutes the three basic registries for Norway’s state management. Kartverket is the cadastre authority in Norway.
Norway is divided into 19 first-level administrative counties, called fylker, and 426 second-level administrative municipalities, called kommuner. The government wants to reduce the number of municipalities and counties (Kommune- og regionsreformen). Last time Norway significantly reduced the number municipalities was in the 1960es. The difference between then and now is that the mergers of municipalities and counties will be done in a digital context. The cadastre is significantly affected by this reform. Real estates and addresses are uniquely defined inside each municipality. When municipalities merges then all real estates and addresses needs to be uniquely define inside the new municipality. Kartverket has developed a technical solution to handle the high number of data that will be altered in the cadastre due to the reforms. This solution makes it possible to manipulate the data in the cadastre to predict how the data will look like after the merges has happen. In this way third party users of the cadastre can get access to predicted cadastre data before the time of merges and prepare their systems for the large alterations in the dataset.
The technical solution that were developed in 2016 was designed to handle the largest thought of merge between two municipalities in Norway, Oslo and Bærum. Merging counties will generate far more alterations in the cadastre then merging Oslo and Bærum. The technical solution will be redesigned this year to handle the increased number of data alterations.
My presentation will focus on how Kartverket will test this technical solution and how to handle large amount of alterations in the dataset from one day to another.
