Realistic Urban Road Network Modelling From GIS Data

Abstract

Starting from GIS data, which are sampled and often inaccurate, this paper presents a method to reconstruct urban road surfaces respecting important geometric constraints selected from civil engineering. We propose a mathematical road surface model based upon road axes and properties. In addition, we introduce a process to produce a mesh representing the roads and the terrain so that roads and terrain match. Experiments and compelling results prove the efficiency of our framework.
