Application of ASTER Satellite in Digital Elevation Model Generation: A Review

摘要

Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is an imaging instrument flying on Terra platform. The distinctive specifications of ASTER satellite such as as easy to access, global coverage, cost-effective data and along-track configuration make it as one of the widely used sources of stereo images. Therefore, since the launch of ASTER sensor many studies have been conducted to investigate the accuracy of ASTER-extracted DEM. This study aims to give a review about the characteristics of ASTER instrument as well as the most important studies on the generation and assessment of accuracy of ASTER-extracted DEM.
