摘要
目前土地利用遥感动态监测已进入实用化阶段,但其自动化程度不高,影响作业效率。本文在使用增强法对两时相的遥感影像自动发现变化基础上,结合两时相影像的分类结果,对变化图斑进行类别标记,然后对标记图像进行矢量化、变化信息提取和统计,从而提高变化监测工作中的自动化程度、减轻工作量。
Land use change detection using remote sensing imagely has been applied practically now,but its poor automatization depressed its application. Based on discovering the change form tow ages＇re imagery by enhancing method and their classification result, this paper marked,ectorized the class of the change span,and obtained and statisticed information from the change image,and consequently alleviated this kind of work.
