摘要
GIS是LBS的位置定位、导航及地图表达的基础技术支撑。针对LBS的固定服务端与移动终端的信息交互需求,提出了平台GIS与移动GIS的概念;针对移动GIS,提出了嵌入式、软件插件组合技术,确定了无线下载的事件表结构;将此用于北京市交通综合信息平台设计,实现了LBS的数据与业务分离、实时信息的自动交互、移动终端的位置确定与表达。
GIS is a basic technical support for position location, navigation and map presentation in LBS. The notion of platform GIS and mobile GIS is introduced due to the demand of information interaction between the server and terminal in LBS. About mobile GIS, the paper presents an integrated technique of embedded system and software plugin and delivers event table structure for wireless downloading. These techniques are applied in design of integrated transportation information platform in Beijing and implement separation of LBS data and operation, auto-interaction of real-time information and the position determination and presentation of mobile terminal.
