Research of Standardization of Extraction Thematic Information from TM Images by Using Optical Composition Method
应用光学合成方法提取TM影像专题信息规范化的研究

The extraction of thematic information from TM images and the selection of versions of optimal composition material have been a subject which needs a deep research in the fields of remote sensing application. But so far there is no set of complete norms and standards to be followed, especially in the quantitative calculating and estimating of colorimetry on image, and in the determination of optimal composition.The problems as mentioned above are studied more deeply by means of traditional multiple exposuring TM image of experiment area, Shuang yang County in Jilin Province. As the standardization of thematic information extraction from TM images is concerned, this paper proposes a theory of optimizing various composition versions by a method of quantitative calculating colour difference, and gives corresponding mathematical model.
