资源简介

摘要: 单天观测数据中很难得到令人满意的植被指数产品,通常采用多天观测合成的方法得到更高质量的植被指数产品。从植被指数合成主要影响因子入手,将植被指数合成算法分为5类,分析误差移除具体方法,总结各类合成算法优缺点。归纳了目前常用的区域或全球尺度植被指数产品及其精度验证。在此基础上展望了植被指数合成算法的研究前景。 关键词: 植被指数合成算法;  植被指数合成产品;  角度归一化合成算法;  MVC     Abstract: Vegetation Index(VI) is one of the main biophysical performances of vegetation,and a useful tool for global and regional detection.It has been used effectively in nuberous of applications,such as detecting change and derieving biophysical properties.However,the daily VI products are not satisfactory because of cloud and atmospheric contamination,so that a compositing technique for multi\|temporal is usally employed.In this paper,firstly,we investigated the contaminatal sources of VI compositing.Secondly,we classified VI compositing algorithms,including the advantages and disadvantages.And then we summarized the commonly used products of current continental or gloabal VI products,and their products validation.Finally,we made a brief review on current compositing algorithm and proposed a prospect in VI compositng method.
