摘要
该文以贵阳市为例 ,利用多时相的TM遥感数据及相关资料对地质构造复杂、地表覆盖类型多样的岩溶山区城市土地利用变化进行了调查和动态监测。基于图像光谱信息特征分析 ,确定了用于贵阳市土地利用变化遥感图像分类的最佳波段组合。利用热红外波段TM 6 。
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.
