摘要:Creating and visualizing DTM based on data from airborne laser scanning become a common practice. Quality of DTM depends on many factors. The paper analyzes the process of creating a DTM in terms of diversity of terrain,the size of grid (the cell size) and methods of interpolation,based on data obtained from the project ISOK for a part (1km2) of the city of Koszalin. Deterministic and stochastic interpolations are used for cellsizes of 0.1 m,0.25 m and 0.5 m. Moreover,the models were compared with DTM obtained from the ISOK. Diversity of terrain has the biggest impact on the quality of DTM based on LIDAR data. Furthermore,depending on the application of the model,it has been checked if reducing the cellsize of the created model GRID affects the quality of the DTM,especially in the context of mapping morhological forms.
