Abstract

Mountain glacier border information is one of the important parameters in detecting glacier changes. One of the major limitations of InSAR applications is decorrelation, arising from spatial baselines of interferometric pairs, time interval of SAR image acquisitions, topographic effects, and noise sources. When the temporal baseline of InSAR pairs is long (such as 35 days and 92 days), the backscattering characteristic changes fast and the coherence of glacier surface will be completely decorrelation. We use the decorrelation due to the glacier surface slope and fast moving as a valuable information to derive the mountain glaciers border. And then an application of one new methodology in Donkemadi glacier (33.08N,92.09E) in Qinghai-Tibetan Plateau is presented using the C-band ASAR data and L-band ALOS/PALSAR data. The result showed that the glacier identification accuracy better than 89% can be obtained considering TM imagery as the ground truth.
