移动GIS关键技术及开发模式探讨

随着移动通讯技术、无线互联网技术和各种移动终端技术的发展以及地理空间信.g-在各行各业的普遍应用,传统的GIS(Geographic Information System)正在逐渐向移动GIS发展,基于位置的服务LBS(Location Based Service)和移动位置服务MLS(Mobile Location Service)已成为移动GIS的主要应用.本文详细介绍了移动GIS的概念、体系结构,论述了移动GIS与传统GIS的区别,详细探讨了移动GIS的关键技术,即嵌入式技术、无线网络技术、地理应用服务器技术、空间数据库技术和移动GIS系统的三种开发模式,最后介绍了移动GIS的主要应用范围,并展望了其发展及应用前景.

Discussion on Key Technologies and Developing Mode of Mobile GIS

With the development of the mobile communication technology,wireless Internet technologies and various mobile terminal technology and universal application of geo-spatial information in all walks of life,the traditional GIS(Geographic Information System)is gradually moving to the mobile GIS,LBS(Location Based Service) and MLS(Mobile Location Service)has become the major application of mobile GIS.This paper introduces in detail the concept and architecture of mobile GIS,as well as the difference with the traditional GIS,discusses in detail the key technologies of mobile GIS,including embedded technology,the wireless network technology,geographical application server technology,geo-spatial database technology and the three developing mode of mobile GIS system.In the end,the paper deals with the major application range of mobile GIS,some problems worthy of further attention in this field are also discussed.
