摘要 构建了基于GIS专题知识引导的土地利用变化自动检测技术与方法,在配准叠加情况下,以T1完整的土地利用类型图斑为单元构建各类别遥感数据知识库,然后以图斑单元计算遥感影像特征统计量,通过与知识库相关数据的比较与匹配,自动检测变化,识别相应的土地利用类别。 This paper developes an automatic detection method for land use changes based on thematic knowledge guided under the condition that one time (T_1) data is existent land use map, and another time (T_2) data is remotely sensed imagery.Experimental results and some actual applications show the efficiency of this method.
