Logic Model of Route Planning Data for Vehicle Navigation
Zhou Cheng-hu · 2008
On the basis of analysis of route planning data structure,this paper proposed a logic model of route planning data for vehicle navigation.First,this paper described features included in route planning data and then elaborates relationships between these features.Finally, it described the attributes of these features.It has been proved that the establishment of the logic model of route planning data is significant for designing of physical storage format for navigation data.Besides,it can direct the conversion and production of navigation data.
