The usage of DEM to create the 3D cadastre

The article presents the analysis of possibilities of using the Digital Elevation (Surface) Models for creation of the 3D cadastre. The authors present the characteristics and meaning of the three-dimensional modelling of objects in the context of solving problems occurring with the traditional two-dimensional cadastre. The paper presents imperfections of the 2D cadastre and indicates possibilities of their removal based on altitude data acquired from the laser scanning. It determines the accuracy of data obtained with lidar techniques and indicates their limitations in specifying the exceeding. As a result of the carried out analysis and theoretical considerations, the authors have indicated the potential possibilities of the usage of Digital Surface (Elevation) Models for the construction of the three-dimensional cadastre system.
