Abstract  

Taking a localized area in Kunlun Mountain as an example,the digital elevation model (DEM) in the highly mountainous area is effectively generated with ERS-1/2 tandem radar interferometry.The accuracy of the achieved DEM is assessed statistically by taking SRTM DEM and USGS GTOPO30 DEM as the benchmark.The main reason affecting the accuracy of interferometry with ERS tandem radar is discussed.The experimental results show that ERS tandem radar interferometry can be used to successfully extract DEMs for highly mountainous areas.It is therefore recommended that ERS tandem radar interferometry might be applied to generate or update DEMs for the western parts of China.
 

Key words:  Tandem radar interferometry      Highly mountainous area      DEM      Accuracy assessment      Correction
