Abstract: Taking the implement of electronic map in vehicle navigation and autonomous driving as the research object, this paper deeply analyzes the closd relationship between the evolution of electronic map and the development of driving technology. The significant characteristics of map data content and model structure at each stage are discussed along with the development of driving technology.In recent years, the iteration of autonomous driving technology has continuously puts forward new requirements for map data, which has further enriched the map content to extent even beyond the scope of traditional geographic information. It requires add more information to spatial dataframe, including environmental perception data, sensor data, driving experience data and so on. Which enables comprehensive management, query and sharing on massive information. This paper proves the rationality and inevitability of the above requirements by reviewing the geographic information transmission model extension. The international data standard NDS is taken as an example to introduce one of the practices. Finally, summarize the relevant progress in brief and presents an outlook of this field.
