Abstract
One of the most important, and at the same time, the most difficult task undertaken in complex process of generation geographic information system is generation of Digital Terrain Model. DTM is primary infromation layer used by systems which depict phenomena in qualitative way. It is also basic element in spatial structure of these systems. In literature there is a lot information concern obtaining terrain data to construct DTM by using photogrammetric and classical methods, but there is almost no information about using satellite methods in such purpose. In this article analysis of compilation technology of DTM generation based on data obtained due to various survey methods, including satellite one, are presented.
