| 摘 要： | 由于高分辨率卫星遥感图像数据量大、空间分辨率高,结构信息复杂,地物同物异谱现象更为突出等等,给专题信息提取技术带来了新的挑战。本研究结合已有的自动提取方法和理论,重点探讨了发现高空间分辨率卫星影像上的光谱知识,并利用这些知识来建立相应的提取方法,来提取土地利用信息,以期为高空间分辨率卫星影像信息的自动提取提供参考。

| Abstract: | As it has the characteristics of larger quantity of data,higher rate of spatial resolution,more complicated structures of information,the existence of different spectrum for the same thing,and so on,High Resolution Satellite RS Imagery brings a new challenge to the extraction of thematic information.Considering the former method and theory,this paper puts its emphasis on discovering the knowledge of spectrum in the high resolution satellite image to establish relative method for the extraction of land-use information,so as to provide references for the auto-extraction of the information from high spatial resolution satellite image. |
