Abstract
In order to study DEM accuracy based on InSAR technology and relationship with terrain factor,with ENVTSAT satellite SAR images in Bam City as an example,DEM was generated by using InSAR technology,and the relationship between InSAR DEM and SRTM-3 DEM was studied,and also focused on study relationship characteristics between InSAR DEM accuracy and terrain factor. The results showed that the elevation difference error of the test zone in InSAR DEM and SRTM-3 DEM is 12.50 m,its accuracy is related to terrain factor.关键词
