空间信息G/S网络访问模式体系架构初探

PRELIMINARY ON ARCHITECTURE OF A SPATIAL INFORMATION NETWORK ACCESS MODEL——G/S

利用Internet发布空间信息已经成为空间信息技术应用发展的必然趋势。借鉴已有的空间信息网络服务体系结构的原理和技术体系,探索研究一种新型的空间信息网络访问模式——G/S模式,并从G/S模式的特点出发,提出并分析G/S模式的架构和技术体系。最后给出一个基于G/S模式的应用系统开发示例,验证了其可行性。

Releasing spatial information based on Internet has become an inevitable trend in the development of spatial information technology application.In this paper we drawn lessons from existing principle and technology system of spatial information network services architecture,and made an exploration research on a new spatial information network access model——G/S（Geo-browser/Spatial Information Servers） model.At the same time,in terms of the characteristics of G/S model,we provided and analyzed its architecture and technology system. In the end of the paper,we also gave a development instance of the system application based on G/S model which proved its feasibility.
