Abstract  

From the contemporary developments of remote sensing and 3S(GPS,GIS and RS)integrated system,this paper introduces some main techniques in remote sensing image understanding field,they are:(1) ground analysis,including analysis of geographical elements in a certain area,relationships between them
and their integration in aspects of spatial distribution features and temporal changes;(2) knowledge acquisition,which lays special stress on knowledge acquisition from GIS Database;(3) credence research,including the determination of the elementary unit for image understanding and utilization of various data.Accordingly,it discusses image segmentation and data fusion respectively;(4) analysis of knowledge base building,including tradeoff making between generality and practicality in building knowledge base;(5) integration of RS and GIS,which specially discusses the soft interface between RS and GIS.For designing this kind of expert system,some key ideas such as integration of GPS,GIS and RS,formation of knowledge base system,application model building etc.are also discussed in this paper.

Key words:  3S integrated system      Remote sensing image understanding      Expert system
