Organization and management of spatial information oriented to mobile smart terminal and its application

This paper proposes an effective spatial information organization and management scheme oriented to mobile smart terminal. The scheme manages spatial data in local GIS server using vector data structure and combining full-relational database and spatial database engine (SDE), achieves spatial data synchronization and sharing between smart terminal and local server through wireless communication network and data synchronization technology. Meanwhile, all spatial data managed by system are divided into two types, base map layer and operational map layer, the former is just regarded as reference information of mobile map in smart terminal. The later includes all of the data layers which are needed to be edited and queried in smart terminal. As an application example, based on the spatial data organization and management scheme introduced above, this paper achieved the organization, management, browsing and querying of Shanghai tourist spatial information oriented to mobile smart terminal.
