面向数字校园的网格LBS体系构架研究

Research on Architecture for Digital Campus LBS Based on Grid GIS

为了有效解决基于位置的服务(LBS)系统中空间信息的共享问题,提出了面向网格计算环境下空间信息网格的数据组织与访问机制模型,构建了以服务为核心,包括定位层、数据层、服务层和应用层的基于网格地理信息系统的校园LBS(CLGG)体系构架。以数字校园为应用实例,研制了原型系统,实现了的区域导航、实时定位、历史路径查询、热点区域信息发布、用户认证与管理等功能,验证了所提出的LBS系统构架和空间信息网格的数据组织与访问机制的可行性和有效性。

The data organization and access mechanism model of the spatial information grid is developed for solving the spatial information share problem.The architecture of campus LBS based on grid geographical information system(CLGG) is proposed for services sharing,which composed of location tier,data tier,service tier and application tier.In the end,a prototype system is designed realizing district navigation and real time location and hot district information release et al.These functions of the prototype valid...
