| Abstract: | This paper focuses on the mountainous Guiyang city, with complicated geologic structure and various land-cover types in Karst area, to investigate and monitor its land-use situation by utilizing multi-temporal TM remotely sensed data and the relative data. Some results and opinions are obtained through the research. Based on analyzing characteristic of spectrum, the optimum combination of bands has been established for TM image classifying to research on land-use variation in Guiyang city. The problem of miscellany between water-body and shadow has been solved using the thermal TM6 during TM image classifying. |
