Abstract:

 In this  paper, an effective vector algorithm for road from digital color raster map is proposed. On the basis of the road vector rules, we apply adjustable frame
tracing algorithm, endpoint (crossover point) judgement and inertial direction to road vector on raster map image. This method overcomes the shortcomings of current methods in
map vector. Experiment results show that it can vectorize the roads of raster map image rapidly and interactively.

Key words: digital raster map, adjustable frame tracing, road vectorization, algorithm design
