摘要：
Research on the issue of climate change and its influence on ice sheets calls for increasing use of methods based on remote measurements and monitoring. Work on the Devon Island Ice Cap in Canada demonstrated the value of interferrometric synthetic aperture radar. Analyses of two image pairs yielded a digital elevation model that could be used for evaluations of ice mass dimensions and characteristics. This method was found to produce metric accuracy with a resolution of 100 m geocoded DEM and with an accuracy of 5.43 m compared to field-derived GPS measurements.
