Abstract: 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 validate the feasibility and validity of the mechanism of the system.
