Abstract

Automatic extraction of roads from aerial photos has been demonstrated in a number of systems, but the systems which display the better capabilities usually rely on manual selection of road starting points. This interaction with a human operator is eliminated by integrating a road-finding module into a road network extraction system. The road finder combines a greedy, edge-based, road-center linker with a smoothness checking program and a post linking process. It is used both for determining where the tracking process is to begin, and for restarting when tracking fails. Results from the fully implemented system are presented
