卫星遥感影像中草地信息自动提取方法的研究

A Study on Automatically Extracting the Grassland Information Method From The Satellite Remote Sensing Images

采用遥感图像处理ERDAS IMAGINE软件和ETM资料,进行了乌恰县草地信息自动提取技术研究。结果证明,选择7―8月时相,ETM432和543波段合成,经几何校正和增强处理,通过交互的非监督分类提取草地信息,结合非遥感资料辅助以及专家知识参与可以获得比较满意的结果。

Using ＂ERDAS IMAGINE＂ Remote sensing automatically information extracting techniques of grasslan images software and ETM images, studied the d in Xinjiang Wuqia county. It shows the result of grassland information extraction from the satellite images of July and August is quite satisfaction using ETM432 and 543 spectral combination, interactive supervised and unsupervised materials and the participation of experts through the ways of image geometric correction, image enhancement, classification method which combined with the nonremote sensing knowledge.
