Preliminary Research on the Application of ERS 1 SAR in Forest

The data sets used for this study were obtained over the Yantai region in Shandong Province by ERS-1 SAR and TM during the period of 1992.Those remote sensing data were geometrically corrected and digitally registered.The relationship between ERS-1 SAR,TM data and forest parameters was analysed by using the method of canonical correlation analysis.The results showed that there was a close correlation between C-bandb of ERS-1 SAR data and crown thickness and average tree height,which indicated that the influence of various forest parameters on ERS-1 SAR image was bigger than that on TM image.So there is a great potential of applying ERS-1 SAR data for estimating forest parameters,even forest volume.
