辽宁锦州市土地利用动态遥感监测方法应用研究

REMOTE SENSING TECHNOLOGY FOR DYNAMIC MONITORING OF LAND USE IN JINZHOU CITY,LIAONING PROVINCE

文章以辽宁锦州市为研究区,以SPOT5为主要遥感数据源,以1∶10000地形图(或土地利用现状图)、野外GPS测量点为几何控制点,应用全数字摄影测量法,进行遥感影像的精确配准、纠正与融合,制作高精度的正射影像图;在G IS支持下,叠合基期土地利用现状图等非遥感数据,采用图像差值法、光谱特征变异法和人机交互解译法,增强提取土地利用变化信息,通过实地调查与核实,取得了良好的应用效果。

Using SPOT5 data as the main data resources, 1 ：10000 scale topographic map （present land use status map） and field GPS survey spots as geometric controlled spots, and full digital photogrammetry to accurately match, correct and fuse remote sensing images, high precision remote sensing orthophotomap has been finished in the Jinzhou city of Liaoning province. Standing by GIS, variation information of land use is extracted by superposing non - remote sensing data such as status map of land use. By way of fact finding and verification, application results are good.
