资源简介

摘要: 基于环境卫星遥感影像,利用随机森林数据自适应探测特性,构建了面向沿海滩涂区域的地物类型分类方法,并以大丰为例进行了实证分析,探讨了基于随机森林方法的滩涂分类的参数选择与精度分析。结果显示:基于随机森林的沿海滩涂地物分类方法分类精度较传统监督分类(平行管道法\,最小距离法和最大似然法)精度提高明显,且具有很好的分类稳定性。 关键词: 随机森林;  遥感影像;  沿海滩涂;  地物分类     Abstract: Taking advantage of the adaptive detection feature of the random forests method,a classification method for coastal tidal flat area has been developed on basis of the HJ satellite images.Two typical areas covering coastal tidal flats,namely the ecological demonstration area of coastal tidal flats and the elk reserve,in the city of Dafeng,Jiangsu Province were selected in this study to showcase the classification effectiveness.The parameter settings and its accuracy were discussed.The results show that the random forests method performs obviously better than other traditional supervised classification methods such as parallelepiped,minimum distance,and maximum likelihood methods,and presents high stability in classification performance.
