遥感影像水体提取研究综述

A review of remote sensing image water extraction

水是非常重要的资源,是一切人类与生物得以生存和发展的重要物质基础,水体提取便于了解现有的水资源概况,有助于对水资源合理的规划及治理,对人类的生活及社会活动具有重大影响。传统的人工方法费时费力,利用卫星遥感数据进行水体位置、面积、形状和河宽等水体参数的信息提取,已经成为一种快速获取水体参数的有效方法和手段。在广泛文献调研的基础上,阐述遥感影像水体提取的基本思想及其发展历程,对学者在水体提取的基本方法和现状进行较全面的综述,分析各种方法的优缺点,说明当前水体提取存在的问题和研究前景,使读者直观了解这一领域并为其研究提供一定思路。

Water is a very important resource,and it is an important material basis for the survival and development of all human beings and organisms.Water extraction can result to easily understand the general situation of existing water resources,thus being conducive to the rational planning and management of water resources and having a significant impact on human life and social activities.Traditional artificial methods are time-consuming and laborious,and therefore satellite remote sensing data is now used to extract water parameters such as water position,area,shape and river width,which has become an effective method and means to obtain water parameters quickly.On the basis of extensive literature research,this paper illustrates the basic ideas of water extraction of remote sensing image and its development course as well as the basic method and current situation of water extraction performed by experts,and makes a comprehensive review and analysis of the advantages and disadvantages of various methods so as to explain the problems of water extraction and research prospect,make the readers understand the situation of this field and provide some ideas for the study in this field.
