【Abstract】 This paper concentrates on how to track and extract the isogram cluster from the map image so that they can be vectorized and inputted into the spatial database rapidly and automatically. The algorithm for tracking and extracting automatically is committed. During processing each isoline, it can automatically recognize and handle the problem of isoline collision. Further more, it can also close the gap on the isoline automatically.更多还原
