隐伏煤田的TM信息提取及地质效果

COMPARISON OF IHS TRANSFORMATION FOR INTEGRATING SAR AND TM IMAGES

在遥感图像上，被巨厚第四系冲积层覆盖的煤田区隐伏地质构造和火成岩分布信息是一种非直接的、微弱的隐伏信息，本文以淮北煤田为实例，探讨了从ＴＭ图像上提取这种信息的可行性与方法，并分析了其地质效果。

In this paper, four kinds of IHS transformations are used to integrate SAR and TM images. The resultant images are evaluated qualitatively and quantitatively. It shows that the quantitative analysis using entropy, joint entropy and average gradient is better than visual qualitative analysis, and provides the way to choose the most suitable IHS transformation for conbining images.
