Figure 3: (a) Interferometric coherence image of Envisat scene. 
The white rectangle indicates the location of Inyltshik glacier. 
(b) Velocity map 4/d?, -- d2. produced by maximizing the MI, 
where da: and dac shows the displacement vector in along-track 
and across-track direction, respectively. 
ACKNOWLEDGEMENTS 
The authors would like to thank Pau Prats and the German Aerospace 
Center (DLR) for providing interferometric process of E-SAR L- 
band images, and Deutsches GeoForschungsZentrum (GFZ) in 
Potsdam for providing the ENVISAT data sets of Inyltshik glacier 
region.
