Digital Elevation Model (DEM) describes the physical and topographic information of earth?s surface. Today, DEM produced by different methods is successfully utilized in many geospatial applications such as gravimetric geoid determination in geodesy, morphology analysis in geology, topographic map production in cartography etc. As known, every year, the new satellites are launched to space and provide the most current information about the earth?s surface with different working principles and different image takin...

This paper aims comparisons of data obtained by different methods of data acquisition. Will present aspects of quality data obtained with Leica total station ultra 802, with GPS equipment from Leica 1200 Series and comparison of these data with altimetry data obtained using LIDAR technology. Measurements were made in ?ag - Par?a area, of Timi? county, on a length of approximately 4 km and over a width of 50 meters left and right from the center. Using LIDAR technology we can realize 3D models, can be detected and ...
