Generation of high resolution digital elevation model (1m) for the University of Baghdad camp using DGPS and GIS

A Digital Elevation Model (DEM) is a digital representation of ground surface topography or terrain. It is widely known as a Digital Terrain Model (DTM). There are many methods for obtaining DEM data, such as terrestrial surveying, stereo Photogrammetry, GPS data and topographic maps. The various applications of DEM and the drawbacks of traditional techniques drastically have increased the significance of using satellite images. In the following paper, the high resolution digital elevation model (1m) had been created using the DGPS, Real Time Kinematic RTK mode with the 3D GIS facility. The region of interest represent the Baghdad university camp which is describe as building complex as well as roads. The final stage of research is to create the 3D viewing satellite imagery.
