基于ENVI的土地利用动态变化分析

Analysis on Land Use Dynamic Change Based on ENVI

选用2期卫星遥感影像数据,利用ENVI软件进行监督分类,提取不同时期土地利用数据库,对监督分类后的结果采用比较法进行对比分析,获取2期土地利用类型的动态变化数据。同时,通过建立解译标志收集相关调查资料,采用人机交互式判读解译,获得研究区不同时期土地利用数据库,以此作为参照,对采用分类后比较法获得的动态变化数据进行验证。

Remote sensing satellite image data of two periods were used,and ENVI software was used to carry out supervised classification,land use database of different periods were extracted,comparison method was used to comparatively analyze the classification results,thus,the dynamic changes data of two-period land use were obtained.Meanwhile,based on the related investigation information data collected by building interpretation symbols and man-machine interactive interpretation was used to obtain land use database in different periods.Then take this result as the reference,the obtained dynamic change data was verified.
