| Abstract: | The application of landsat TM digital image on vegetation cover research is studied and the approaches of selecting a subset of a TM multi-image are discussed for enhancement by false-color compositing and ratioing. Vegetation cover informations are extracted successfully by ratioing and Karhunen-Loeve transform. |
