摘要：

The operational feasibility of using Radarsat ScanSAR data to estimate the spatial distribution of snow water equivalent (SWE) in the La Grande River basin, a large hydroelectric complex located in a subarctic climatic region (Northern Quebec, Canada), is demonstrated for the 1998-1999 winter season. The methodologies developed for this project have been implemented within a MapInfo(TM) application that has been named EQeau. Analysis of ScanSAR images has shown that they can yield results similar to wide mode images, despite their lower resolution. On a sub-basin level, EQeau and ScanSAR images have given similar SWE (+/-1-12%) to those derived from Hydro-Quebec snow lines for January and March 1999.
