Omfattning och differenser av gränshävder kontra registerkartan i Boda, Skellefteå kommun

Sammanfattning: 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. A subsidiary aim of the study was intended to investigate the problems that can occur when measuring with GNSS in a forest environment. Another subsidiary aim were to describe what legal protection the boundary conditions has been and find out how usucaption today is handled by the Cadastral Authority. Measurements of all usucaptions have been performed. This process of measurement was performed with GNSS instruments and network RTK as the measurement method. In order to answer how usucaption is currently handled an interview study was conducted, in which 7 people were interviewed. The results of previous studies resulted in forest density has the greatest impact on GNSS survey in the forest environment. After processing the data, the results concluded that differences in tree height are the most common usucaption in Bodan. Then an estimate of the deviation between all usucaptions and the cadastral index map was made. This resulted in the largest maximum deviation between usucaption and cadastral index map was 11,463 m and the average deviation of all usucaption against the cadastral index map was 2.074 m. The conclusion drawn after the course of the work was that the longer boundary lines, the greater the distance between claimed border and the cadastral index map. By interpreting and describing the text of § 18 JP, 14 Ch. 5 § FBL and immemorial custom has the legal situation of usucaption been answered.  The result was that usucaption today has a relatively weak legal protection, it is only when the boundaries are not legally defined the Cadastral Authority is using a usucaption to determining a boundary. By using laws principles § 18 JP, 14 Ch. 5 § FBL and immemorial custom, a boundary is moved if there is an agreement, however, requires a very high degree of proof for this to be implemented. From the interviews, the result was that usucaptions is not often used to decide a new boundary. The usucaptions is instead used to show the property owners where the approximate boundary is. An agreement between the property-owners is the most common solution on how usucaptions are handled.
