This paper presents our recent research on augmented maps where unprepared paper maps are used and Geographic Information System serves both as reference database and augmentation data. We use road intersections to register paper map and GIS so several paper maps of the same city whatever their styles and colors can be augmented using the same reference database. We present a new road extraction method to get better road intersection for a quick initialization and a faster method to register maps and GIS. Different maps are used to demonstrate the effectiveness of our method.
