| 摘 要： | 在对研究区背景本底知识和遥感数据光谱知识充分分析的基础上,挖掘谱间结构,得出各典型地物的光谱空间特征及相互分离规则。结合原有GIS数据,用地学知识和DTM模型纠正初步分类图,得到较理想的分类结果。尝试提出各专题信息分层提取,分类结果加权叠加的方法。

| Abstract: | Based on the background knowledge of study area and the spectral knowledge of remote sensing image, the structure of different spectra had been digged, and the breakaway regulation of representative features had been obtained. Combined inhere GIS data, the more perfect classification result can be obtain. The method of extracting thematic information by considering target features, and weighted-overlay class result had been put forward. |
