摘要
以山东省龙口市为例,利用ERDASIMAGINE图像处理软件,通过对遥感图像进行图像增强、图像正射校正,融合等处理,得到1∶1万正摄遥感图像。对龙口市所辖区域进行实地外业踏探,建立土地分类的影像解译标志。此外,运用MapGIS地理信息系统软件,通过人机交互目视解译,对目标地物分层矢量化,提取龙口市土地利用现状信息。并在此基础上对研究区的土地利用现状及空间分布特征进行了分析,为当地土地资源的合理开发利用提供了基础数据。
Taking Longkou City in Shangdong province as an example, the DOM with the scare of 1：10000 is gotten by the imagine processing of enhencement ,geometric correction and resolution mergence by using ERDAS IMAGINE image conducting software. Land interpretation symbol has been established based on the site investigation in Longkou city. By using MAPGIS software, through interactive interpretation between people and computer, land in target areas are vectorized and present information of land utilization has been obtained in Longkou city On these basis, present condition of land utilization and spacial distribution characteristics are analysed, which provide basic datas for local government in developing land resources reasonably.
