摘　　要：提出了利用主成分分析方法有效地复合纹理和结构信息 ,从Landsat7ETM+ 全色数据中直接提取区域尺度的城市建筑信息的新方法 ,并在此基础上评估了Landsat7ETM+With the principle component analysis (PCA), this paper preserts a new approach to effectively incorporating texture and structure information into the classification procedure to detect urban building in Beijing by using Landsat7 ETM + panchromatic image. The results indicates that the texture and structure information are effectively incorporated into the classification procedure with PCA and are helpful to detect urban building to achieve the accuracy of 81.33%. Besides, the results show that Landsat7 ETM + panchromatic image can be regarded as a good alternative of spot panchromatic image in urban building detection with the identical ratio of the two results reaching 89.42%.
