TM数据的Kauth-Thomas变换在盐渍土分析中的作用——以阳高盆地为例

The Effect of Kauth-Thomas Transformation of TM Data in the Analysis of Saline Soil——An Example in Yang Gao Basin

本文就经过Kauth-Thomas变换的TM数据用于雁北阳高盆地盐渍化程度分析进行了探讨。通过模拟TM数据和TM影像数据进行变换分析,并与标准假彩色合成和K-L变换比较,取得了较好的结果。

This paper discribes a test in which the TM data in Yang Gao Basin, YanBei are processed with Kauth-Thomas Transformation and analysed for the degree of salinization of soil. The analysis of transformation is done with simulated TM data and TM image elata. After comparison with standard false color TM image and the image after K-L Transformation, the result is the best between them.
