摘要

所提出的结果显示了如何从ERS串联INSAR数据测量和计算冰川速度。利用GIS软件包Arc/INFO中已有的和新实现的模块，开发了一种用于冰川速度计算的半自动算法。使用外部DEM将速度分解为冰川的流动方向。计算了斯匹次卑尔根岛Isachsenfonna、Akademikerbreen和Nordbreen冰川的速度场。

Mapping glacier velocities at Spitsbergen using ERS tandem SAR data

The results presented show how glacier velocities can be measured and calculated from ERS tandem INSAR data. A semi-automatic algorithm using existing and new implemented moduls in the GIS package Arc/INFO has been developed for the calculation of glacier velocity. The velocities are decomposed into the flow direction of the glacier using an external DEM. Velocity fields for the glaciers Isachsenfonna, Akademikerbreen and Nordbreen at Spitsbergen have been calculated.
