The cadastral index map is a great benefit to the surveying and governments. The map's main purpose is to show how the overall cadastral division looks in Sweden. The lack of quality of the cadastral index map dose not allows property-owners to know where to draw the boundary between their and others' property. In order to know where to find the boundaries between two properties, is it up to the property-owners themselves (self or in company by the other property-owner) to construct various Usucaption at the boundaries. The main objective of the study is to verify the existence and extent of Usucaption on forest properties in Bodan, a village outside Skellefteå.
