摘 要: 冰川流动速度是极地物质平衡的重要参数,目前国际上通用的冰流速测量软件有很多种。本文选取四款常用的光学影像冰流速测量软件进行比较分析,包括:Imcorr、CIAS、COSI-CORR和MicMac. 介绍四款软件的原理,并用Landsat影像对这四款软件进行测试。结果表明:COSI-CORR和MicMac 的测量精度最高,Imcorr精度次之,CIAS精度最差;运行时间方面,Imcorr所需时间最少,之后分别为COSI-CORR、CIAS和MicMac;测量范围方面,MicMac最大,CIAS和Imcorr相当,COSI-CORR最小。
关 键 词: 自然地理学;测量软件比较;Imcorr;CIAS;COSI-CORR;MicMac

Abstract: Ice flow velocity is an important parameter of the Antarctica mass balance and many kinds of ice velocity measurement software are widely used in the world. In this paper, four kinds of commonly used ice velocity measurement software based on optical remote sensing images are selected to evaluate their performance, including Imcorr, CIAS, COSI-CORR and MicMac. The principles are first introduced, followed by the experiment on Landsat images. Results show that in our test region, COSI-CORR and MicMac have the best measurement accuracy, followed by Imcorr and MicMac; when it comes to the runtime, Imcorr performs best, followed by COSI-CORR and CIAS, and MicMac is the most time-consuming; as for the measurement region, MicMac covers the largest, then CIAS and Imcorr, and COSI-CORR has the minimum coverage.
Key words: natural geography; measurement software comparison; Imcorr; CIAS; COSI-CORR; MicMac
