网络GIS及其内容体系和应用分析

Studies on Conceptual Framework,Content System and Applications Analysis of NetWork GIS

众多研究人员在网络GIS的研究方面都习惯将其内容简单化为WebGIS或者Internet/Intranet GIS。实际上,WebGIS和Internet/Intranet GIS在数据模型、网络架构、体系构建和功能部署等方面都有较大的区别,这种将We-bGIS和Internet/Intranet GIS统称为网络GIS的做法本身就有缺陷。本文以网络和分布式计算技术为基础,从“广义”和“狭义”的角度对网络GIS的概念框架、内容体系和应用等几个方面做了重构研究,以期推动网络GIS的研究进展。

Contents of Web Geographic Information System research are, habitually, simplified as WebGIS or Internet/Intranet GIS by most researchers. In fact, there are many differences in data model, Web structure, function deployment between WebGIS and Internet/Intranet GIS. Therefore, if Web Geographic Information System is called by the name of WebGIS or Internet/Intranet GIS, there exist disadvantages in essence. On the basis of web and distributed calculation technology, this thesis achieves much restructure researches on conceptual framework, content system, applications analysis and existing problems of Web Geographic Information System in terms of broad sense and narrow sense, so as to promote Web Geographic Information System research.
