A Mobile Storage System for Massive Spatial Data

This paper aims at the solution to problems of large amounts of data storage, low efficiency calculate and poor user experience which actually exists in GIS application on mobile devices. In order to solve these issues we use GIS technologies including spatial data organization, map browser, and spatial index. We focused on the research of how to effectively utilize system resources and rational and efficient out organize the spatial data. What’s more, we improved the R-tree indexing algorithm to establish a rapid spatial index structure and used hierarchical classification techniques to optimize the efficiency of the real-time visualization of spatial data for mobile devices.

Structure and Design of Intelligent System for Police GIS Spatial Database

According to the application of intelligent system for police GIS ,it needs to query and locateassist police,command and dispatch,patrol management and so on, According to the characteristics of police spatial information, All the spatial data needs to be unified storage. This paper designs the spatial database based on Geodatabase, then the database management for police is constructed and to achieve a unified and efficient management, so it provide an effective solution for the spatial data organization and management.
