像斑的遥感影像土地利用变化检测方法

提出一种有GIS数据辅助的以像斑为对象基于不同时相非同源的遥感影像变化检测方法,这种方法属于特征级的变化检测,以影像像斑为对象,突破了以往变化检测对数据的要求与限制,改变了传统检测方法对于遥感影像数据的要求同源的模式.通过土地利用图和遥感影像的精确配准套合获取影像像斑,再利用聚类算法按类别进行样本的更新,利用更新后的样...

Land Use/Cover Change Detection Using Disparate Image on Land Use segment

Based on the analysis and summarizations of researched home and aboard,the dissertation focused on land use\cover detection using disparate images on land use segment,which belongs to Feature class of LUCC.It should be pointed out that the researches must be focus the disparate remote-sensed imagery other than traditional methods of the same kind remote-sensed imagery.The land use span was expressed by vector polygon along with raster region.First getting the sample of this type of land use classes,then det...
