摘要
详细论述了使用TM卫星遥感影像提取土地覆盖信息的技术与方法。针对山区地形复杂、常年多云雾、分类难度大的特点,着重加强对影像的地形校正和去云处理,以此来提高图像分类精度。研究结果表明,这种方法能有效地提取TM卫星遥感土地覆盖信息,特别适合我国南方山区土地覆盖信息的提取。
Some comprehensive methods and techniques of extracting the information from TM data are described, specially a improved method of land cover classification by using TM images. In mountain area, with high elevation and steep slope, in order to improve plecision of classification, referencing topographic normalize and cloud removal of TM data. The results show that much good information can be derived from TM images by using these methods and techniques ,the methods is especially suitable to apply in this south mountain area.
