摘要
GPS车辆跟踪或导航系统中,路径拓扑结构是路径分析问题的基础,它描述了网络中点、线、面的连通关系,它也是矢量地图跨区域连接问题的必备要素。针对GPS车载导航系统对空间数据的处理、动态方向指示、图层叠加拼接、及车载端口有限系统资源等特定的要求,研究并实施了适应于跨平台的“GPS”系统集成方案的路径拓扑和构架。
In the GPS tracking and navigating system, the path topology structure is the base of path analysis. It can describe the connective relation of dot, line and surface in the network and it is also an essential element of link problem about the vector map spanned regions. According to the special requirements of dealing with the spatial data, indicating the dynamical direction, stacking and splicing figure layers, and the finite system resource of the port in GPS vehicle navigating system, this paper studied the path topology and integration which fit the integrated scheme of GPS system and put them in practice.
