Automatic Extraction of Road Intersections from Raster Maps Yao-Yi Chiang, Craig A. Knoblock, and Ching-Chien Chen   View Paper (PDF)   Return to Session 8: Image and Shape Analysis - User Interaction Abstract Numerous raster maps are available on the Internet, but the geographic coordinates of the maps are often unknown. In order to determine the precise location of a raster map, we exploit the fact that the layout of the road intersections within a certain area can be used to determine the map's location. In this paper, we describe an approach to automatically extract road intersections from arbitrary raster maps. Identifying the road intersections is difficult because raster maps typically contain ... ©2006 Association for Computing Machinery
