The Introduction to the Key GIS Technology in the Spatial Information Service System for Mobile User

This paper introduced the birth background of spatial information service for mobile user, proposed the solution way based on MAS architeeture, diseussed the study of the GIS realization technologies and methods, and prospected the influence and the future of the GIS and spatial information service. In the introduetion of the solution way based on MAS architecture, the birth background of this technology was introduced firstly, then the individual architecture of spatial-info agent arid the theory of cooperation by MAS was presented emphatieally, lastly the ideas about the mamagement, maintenance and update of spatial-Info agent was mentioned. In the paper, the 5 key GIS technical researches was presented, which were the magnanimity spatial information intelligent search and pick-up, the theories, arithmetic, teehnology and archetype of the interoperation between different GIS software. GIS WAP Service faced on 2.5G upward current mobile equipments, the voiee/short-message spatial information communication methods based on SMPP and CMPP. and the open integration teehnical spatial information service system based on spatial-info agent and MAS architectures.
