Abstract: InSAR coherence is very low in the watershed area. The TXOR algorithm and multiple radar coherence images were used to identify the lake boundaries near Siling Co in Tibet. The comparison between the InSAR extracted boundaries and the optical images demonstrates that the method is useful in extracting watershed areas on a large scale.

Key words: Interferometric synthetic aperture radar(InSAR); coherence; lake boundary identification
