摘要
移动导航定位系统是对移动目标实施自动动态导航的系统。重点分析了空间矢量数据的存储与管理、空间拓扑关系构建、空间索引构建、定位数据接收与处理和地图匹配等关键技术。最后,介绍了基于PDA移动导航定位系统的实现及其应用。
The mobile navigation and positioning system is used to carry out dynamic auto-navigation of mobile objects. We placed emphases on analysis of the key technology ＇in the system, including spatial vector data storage and management, spatial topology generation, spatial index generation, receiving and computation of positioning data, map matching etc. At last, the paper presents the implementation and application of the mobile navigation and positioning system based on PDA.
