移动环境中空间信息服务模式研究

Geographic Information Service Model in Mobile Context

移动环境中,空间信息服务的独特之处表现在技术的先进性与内容的个性化。通过研究弄清“移动”这个与“空间”密切相关的主题如何为空间信息服务的进一步发展与应用提供新的途径和方法,可为今后不同类型的相关系统在基于空间位置的广泛服务领域应用提供初步经验。本文首先分析了“移动”的涵义与技术驱动下空间信息服务模式的改变;其次比较了移动地理信息系统(M-GIS)与传统GIS的异同;最后提出一个适应于移动环境的空间信息服务技术体系,并给出研究实例。

In mobile context spatial information services are characterized of advanced technologies and individualized information. A research that how the topic of mobility, which is completely different but tightly relevant to space, provide new approaches and methods so as to improve the further development of spatial information services, will accumulate a basic experience for different types of relative information systems in the wide fields of location based services, Firstly the paper analyzes meanings of mobility and changes for spatial information service pattern driven by technologies. Secondly it describes differences and correlation between M-GIS and traditional GIS. Finally it sets a technical framework of spatial information services in according to mobile context and provides a case study.
