摘要：The accuracy of digital height models (OHM) is primarily influenced by thepoint-density and the terrain-type. The influence of the interpolation methodis less important. The amount of the needed time for data-acquisition anddata processing depends strongly on the number of points. That is why thereis a great interest in reducing the data to a number which is adequate fora predefined accuracy in terrain-representation.The report describes procedures and programs for computer-aided and analyticalinstruments, which allow data-acquisition in optimal point-density. Anexperimental test shows the efficiency of the proc~dures.
