Accuracy Evaluation of Dem Derived by Terrasar-x Data in the Himalayan Region

In the past few years, the Himalayan region has experienced a number of floods from glacial lakes, and the neighboring areas were severely damaged. Therefore it is important to continue monitoring glaciers or creating simulation of floods to prevent the damages in those regions. The DEM is very useful for studying these hazardous problems. In this study, we tried to generate DEM by TerraSAR-X images for conducting InSAR processing and evaluating the quality of the DEMs by comparing them with SRTM data. DEM generated by TerraSAR-X image could acquire more detailed surface information of the mountaneous region. The end and side of the moraine were recognizable with TerraSAR-X DEMs. It is expected that the InSAR DEM would be highly useful for monitoring purposes in the mountainous regions. * Corresponding author.
