【摘要】 土地利用调查中,遥感数据被作为调查的基础数据源,开始取代传统的航片或地形图,以SPOT5数据应用最多。基于此,介绍了SPOT5卫星遥感数据的特点,并结合土地利用调查的有关要求,对SPOT5卫星影像数据的正射校正、影像融合、彩色合成等方法进行了探讨。更多还原

【Abstract】 In land use survey,remote sensing data as survey’s basic data source begins to replace the data of traditional aerial photo and topographic map,mostly applied SPOT5 data.Based on this,this paper introduces SPOT5 satellite remote sensing data’s characters,probes into the methods of orthophoto rectification,image fusion,color integration,and so on,combined with the relative requirement of land use survey.更多还原
