Accuracy assessment of SRTM data case study: New Cairo, Hurghada and Toshka in Egypt

Abstract

Nowadays, the development in Egypt needs up to date maps. SRTM data were collected during 11-day mission in February 2000. Since this date, the SRTM data were available for the whole world. On the other hand, the accuracy these SRTM height data was not tested in Egypt. So, the current research paper is focused on the Accuracy Assessment of SRTM Data in Egypt. In this context, eight sights in Egypt were investigated. These eight sights lie in three different parts of Egypt. Grid leveling by ground surveying was captured for these eight sights. Then accuracy assessment between the actual field data and the SRTM data was made. The results shows that, the accuracy of SRTM data after removing systematic errors from the SRTM data was in the range of sub-meter in flat terrain and three meter in rough terrain. © 2010, INSInet Publication.
