Abstract
The results of the research project "Checking and Improving of Digital Terrain Models" of the European Organization for Spatial Data Research (EuroSDR) are presented. The various solutions to the problem of determining the geometric quality of Digital Terrain Models are explained. Test material consisting of three different Digital Terrain Models (derived by automated photogrammetry, by digitizing of contours and by airborne laserscanning) and stereopairs have been used by several research groups in order to check and improve the provided Digital Terrain Models. Accurate reference data (derived by means of low altitude imagery and by ground surveying) have been used by the pilot centre in order to evaluate the results of the participants in the test.
