电子地图在数字社区中的应用

利用计算机处理、表现地图信息数据,将地图信息数字化后生成电子地图,应用于社区的安防报警、物业管理、数据查询、公共服务等方面,可极大提升数字社区的综合管理能力.基于电子地图的应用有两个难点:图形的组织与显示;海量数据的存储与开发,本文采用MapX控件实现图形的分层与叠加,数据与图形的绑定;运用Oracle Spatial模块完成海量数据的存储与应用,以及与常规数据的并存存储,开发了基于电子地图的应用.

Application of Electronic Map in the Digital Community

Information data of a map being dealt with and shown by computers, and when the information be digitalized, an electronic map is composed. It would greatly improve the management ability of the digital community when the electronic map be applied in the community management departments such as alarm, property management, data inquiry, common service etc.. There are two difficulties of the application based on electronic map: to organize and to show the pictures; to store and to develop the mass data. In this paper, the first problem was rea- lized by MapX control, and the second one was solved by Oracle Spatial module, and thus the application base on electronic map was developed rapidly.
