Abstract:

The measurement of ice velocities of the Antarctic glaciers is very significant to the study on the Antarctic ice and snow mass balance, the Antarctic environment change and its influence on the global environment. This paper discusses the principles and methods of monitoring the glacial changes by means of multi temporal satellite images of remote sensing. After performing the geometric rectification, registration and overlay processing on different temporal remotely sensed images in the Ingrid Christensen Coast, it measures and calculates the average ice velocities of the Polar Record Glacier and the Dark Glacier. Besides, it preliminarily analyzes and evaluates their changing characteristics.
