Coordinates of Boundary Points in Norway
Helge Nysaeter
This paper focuses on todays practice concerning cadastral surveying, and calculation of coordinates of cadastral boundaries, in Norway. Cadastral surveying is in Norway performed mainly by public surveyors, employed by the municipalities. These are obliged to follow relatively strict demands concerning measurements and computations, issued by the mapping authorities. However, these demands may be a bit outdated and not that well adapted to the newest technologies. I discuss the need for an adjustment computation with blunder detection and reliability analysis, when RTK-GNSS is the preferred measuring technique. This is also compared to practice in other European countries. I also discuss whether the surveyor should be given more freedom to choose the optimal method of measuring and calculation of coordinates in each situation. This question is connected to the question of formal qualification demands for the cadastral surveyor. Finally, I discuss the significance of the coordinates of the boundary points in the Norwegian cadastral system. This is also compared with some other countries.
