摘要
本文简要地介绍了ＲＳ（遥感图像处理系统）和ＧＩＳ（地理信息系统）技术及其集成的基本概念和方法。讨论了ＲＳ和ＧＩＳ技术及其集成的内在涵义、相互关系，认为ＲＳ是ＧＩＳ重要的外部信息源，是其数据更新的重要手段，尤其对于全球性的环境变化研究和地理动力学分析，更必须有ＲＳ所提供的覆盖全球的动态数据与ＧＩＳ的结合。反之，ＧＩＳ则可以提供ＲＳ所需要的一些辅助数据，以提高ＲＳ图像的信息量和分辨率，同时，ＧＩＳ可以将实地调查所获得的非遥感数据与遥感数据结合，从而提高ＲＳ图像处理和解释的精度。而ＲＳ和ＧＩＳ技术的结合集遥感、地理信息系统技术的功能于一体，构成高度自动化、实时化和智能化的地理信息系统，是空间信息适时采集、处理、更新及动态地理过程的现势性分析与提供决策辅助信息的有力手段。
The basic conceptsand methods ofRS(rem ote sensing im age processing system ) and GIS(geographic infor- m ation system )and theirintegration areintroduced.Thetechnology and integration ofRSand GISarediscussed fortheir inherentm eaning and relationship to each other.RSisconsidered asan im portantexternalinform ation source ofGISand a usefultoolforrenewing data,especially to globalenvironm entalchange research and geographic dynam icalanalysis.It is im perative to com binedynam icaldata covering thewhole world region provided by RSw ith GIS.On thecontrary,GIS can provide som e supplem entary data and im prove the amountofinform ation and resolution.Meanw hile,GIScom bines un-rem ote sensing data aquired through field investigation with rem ote sening data,so thatitcan im prove theprecision ofRSim age processing and intertation.The integrated com bination ofRSand GIStechnology includes rem ote sensing, geographic technology,which constitutesgeographicinform ation system with high autom ation,and intelligence.They are potentw aysofanalyzing collection,treatm ent,andrenew ing adynam icalgeography processand providing supplem entary inform ation ofdecision.
