Abstract :
The paper deals with the problem of comparison of Digital Terrain Models, which were gained by different technologies for the same area. In the article a test area is examined and the data generated from laser scanning, topographic mapping and photogrammetric evaluation of aerial images are compared. In the article the scope, the accuracy and the reliability of the different methods are compared and evaluated; the results are demonstrated visually and in form of tables.
