| Abstract: | Today SAR is in one of the active in the rapid development of remote sensing technology, more convenient of stereo SAR technology can wide the range of DEM, this technology has begun gradually been widely used in the actual production. ERDAS software because of its powerful occupying most of the market share of the professional remote sensing image processing software. This article focuses on the general steps of SAR data processing, to generate DEM＇s principle with ERDAS software system to extract the DEM process. The results show that the use of this software is able to quickly and efficiently extract the DEM data, to achieve better efficiency. |
