Abstract
Creating Digital Terrain Model (DTM) is one of the most important goals, which are to be considered in Spatial Information Systems. Usefulness of satellite systems with combination of classical methods gives an opportunity of horizontal and vertical measurements. Nowadays, Digital Terrain Model becomes a standard geospatial product and is the main information layer used in Geographic Information Systems. This paper presents the processes of acquiring and updating data using GNSS satellite techniques, which enable easy and quick automatic measurements, as well as innovative technology to determine the position coordinates using the Leica Smart Station technology. The results of measurements of Total Station and RTK are also presented. Based on these measurements, the GRID DTM was created using Surfer 9 software and comparative analysis of the results were performed. It was found that the results obtained from satellite measurements are similar to tacheometric results. Data obtained from RTK GNSS measurements allowed to reproduce DTM. Comparing to the model developed from tacheometric data, for surface mesh created as GRID, it was found that an average height coordinate difference was of the order of 0.05 m.
