摘要
结合车载导航应用,研究导航数据模型及数据交换格式的发展,探讨路网与导航系统的关系.在研究GDF4.0标准的基础之上,结合实际对导航路网数据模型及其应用进行了研究.通过对道路网数据的提取结合数据模型,以GIS桌面软件SuperMap Deskpro为作业平台,实现了最佳路径分析,并介绍了立交桥符号的设计与实现.
The geographic data of navigation is the basis for navigation applications.This paper combines with the applications of vehicle navigation,studying the development of the navigation data model and data exchange format and discussing the relationship between road network and the navigation.Based on the research of GDF 4.0 standard,combined with the actual studied the navigation road network data model.Through the extraction of road network data and combination of data model,achieves the best path analysis on the platform of GIS software SuperMap Deskpro,describes the design and implementation of the overpass symbol.
