| Abstract: | This study evaluates the potential and feasibility of measuring, mapping and monitoring of forests damage caused by pine caterpillars (Dendrolimus punctata Walker) using Landsat Thematic Mapper (TM) data. The composite images using TMS/TM4, TM4/TM3 band ratios with TM2 band are rich in vegetation and forest damage information. The TM5/TM4 band ratios difference data set was found to be strongly correlated with ground-based measurements of forest damage in Zhejiang province. Therefore, it is proved that Landsat Thematic Mapper (TM) data is sufficient to monitor and detect forest damage caused by insect and diseases. |
