摘要
介绍了运用GPS控制点纠正遥感影像的全过程,在ERDAS平台对传统的窗口对窗口的视图式纠正方法和基于文件的GPS纠正方法作了比较,就其存在的优缺点进行了分析。对运用GPS进行遥感影像纠正的可行性进行了分析,对这种方法运用于西部地区或沙漠地区的遥感影像纠正的可行性作了初步的设想。
The author describes how to use GPS graphic control point （GCP） to correct remote sensing image inthis paper. Under the planform of ERADAS the author makes a comparison between two correction methods--the View to View model and GPS-based file mode. The author also conducts the feasibility analysis on using GPS to correct the remote sensing image, and makes an initial assumption of the feasibility to apply this method in the correction of remote sensing image in western or desert areas.
