ETM图像水体信息提取
Water Information Extracting from the ETM Images
本文应用云南省南部地区的ETM遥感影像图，对该区域内的水体信息进行提取。以G48C004002为典型示范区，结合交互式矢量化和野外验证成果对各种方法进行分析选优，最后提出了一种水体提取的新方法：缨帽变换湿度分量法，经验证该方法满足提取要求。本文还对去除影响因素进行了深入的探讨，例如对于阴影的去除和混合像元影响的去除。
Using the remote sensing data “ETM” of the southern part in Yunnan, this article extracted the water information of this region. This article had chosen the G48C004002 as a typical demonstration zone, combining the interactive vector field and the results from the wild, choose the best of the extracting methods. Finally, a water extraction method “Humidity component of Tasseled Cap transformation” was given out; by certification this method meets the requirements of extraction. Then this article discussed how to remove the impacts of extracting, such as the shadow and the mixed-pixels.
