Paper Abstract

This paper focuses on the topography measurement of island with satellite remote sensing. In this paper, remote sensing stereo images from Cartosat-1 satellite are used to survey the topographic information of island. Ground control points (GCPs) data are collected through on-site measurement. Then, some distributed GCPs are selected for remote sensing image processing. The digital elevation information (DEM) is extracted from Cartosat-1 remote sensing data by DEM extraction processing. And then, contour, slope and aspect are calculated based on DEM information. Finally, some ground control points is selected to validate the accuracy of topographic information. The results show that the accuracy of topographic information obtained 4.32m at horizontal position and 6.24m at vertical elevation accuracy.
