摘要
本文分别介绍了指数模型法、监督分类法和决策树法三种不同水体遥感提取方法的过程及原理,并以洞庭湖水域的水体提取为例,比较了三种方法的实现异同,从而为在不同时期和不同用途时采用最佳的水体提取模型提供一定的依据。
In this paper, the procedures and principles of three different water extraction methods: index modeling, supervised classification and decision are presented respectively. By taking Dongting Lake as an example, a comparison among these three methods is made and thus a certain basis is provided for the use of the optimum water extraction models for different purposes at different time.
