摘要
地理信息系统于20世纪60年代由加拿大测量学家R.F.Tomlinson提出.随着社会经济发展的需求和IT技术的快速发展,地理信息的处理、分析手段日趋先进,其应用开发分别经历了GIS、网络GIS(WEB GIS)和网格GIS体系结构的演进.在网格GIS的基础上,云计算GIS应用开发将成为新的发展方向,这充分表明地理信息系统开发应用将随实践的发展而不断演进.
The concept of Geographic information system was first put forth in 1960＇s by R.F. Tomlinson, a Canadian merologist. With the ever-increasing needs for socio-economic development and the fast growth of IT, means for geographic information analysis and treatment are getting more and more sophiscated. Its application development has gone through mainly three stages： GIS, WEB GIS and GRID GIS. Based on WEB GIS, the application development of cloud computing GIS is becoming a new development trend, which shows quite clearly that the application development of the geographic information system evolves with the development of social practice.
