FEASIBILITY OF VERY HIGH RESOLUTION OPTICAL SATELLITE (VHROS) STEREO IMAGERY FOR TOPOGRAPHIC MAPPING
Prof. Ismat M. Elhassan*
ABSTRACT
The importance of Ground height determination is valid for various applications, especially in the fields of earthwork calculations needed for different constructions such as highways, railways and many other infra structures and in contour map production as well. Topographic maps and Digital Elevation Models (DEM) covering large areas can be generated by means of optical images taken from space. Very high resolution optical satellite stereo pairs of ground resolution better than one meter are now available and were tested for height determination accuracy. This paper is an attempt to collect and analyze test results of Very High Resolution Optical Satellite (VHROS) images as far as ground height accuracy and to validate their potentials in producing large scale topographic maps. Such VHROS include IKONOS, QUICKBIRD, Worldview-3, Pleiades and GeoEye-1 Satellite imagery.
