Modeling and Implementation of Navigable Geographic Framework Data——Construction of road network based on fundamental geographic data
Guizhi Wang · Geomatics world (Lemmer) · 2007
Navigable geographic framework data functions as the geo-spatial referencing framework that integrates traffic maneuver and POI(s). The main difference between the navigable geographic framework and the traditional fundamental geographic data is that the former emphasizes the connectivity of the road network. It should describe the logical traffic flow carried by each road element,especially around complex flyovers. This paper studies the data model of navigable geographic framework data,and proposes a method for constructing road network based on multi-scale fundamental geographic data.
