Prof. Ismat M. Elhassan*


Topographic variation description obtained from topographic maps or Digital Elevation Models (DEMs) is quite commonly used for several applications especially in the fields of Geographic Information Systems (GIS) and civil engineering projects. Many procedures are now used to prepare height data for topographic maps and DEMs formation. These include classical ground surveying methods: levelling plus triangulation or traversing, total station and stereo images from air photos captured by aerial and drone cameras. All these techniques would give very high accurate elevations, but they are very much time consuming and labor intensive. Recent techniques use space stereo imageries to produce ground point elevation. One of the high resolution satellite imageries (HRSI) capturing stereo images is the satellite borne WorldView-3 (WV-3). Although such remote sensing methods save a lot of time and expenditure the limitation is the height accuracy obtained. This paper analyze (instead of compares) the elevation accuracy. that can be derived from WV-3 stereo imagery using elevations determined by total station as reference. Test results show that WV-3 stereo imagery can allow height accuracy that can be used for several applications including production of 1:5000 scale topographic maps, saving both money and time.
