| 摘 要： | 运用K-L变换和NDBI(Normalized Difference Barren Index)指数法,对试验区--沧州市及其周边地区的ASTER遥感影像进行处理,然后分别对两种方法处理后的图像采用最小距离法监督分类,提取城市用地信息,并对分类后的图像进行对比,结果表明:NDBI指数法对城市用地信息提取的效果较好.

| Abstract: | The ASTER image was used to extract the city land use information of the research area by K-L transform and NDBI(Normalized Difference Barren Index) method.This paper implemented the supervised classification using minimum distance method for the processed image by the above two methods,and extracted the space information of city land use.Then a comparison was made between the two classified images.The result shows that NDBI method is better at extracting the space information of city land use. |
