    Abstract:

    Layering map image by colour, which is one of important steps for automatical recognizing map image by computer, is researched in this paper. The algorithm for layering is proposed, and some problems about layering efficiency and effect are discussed.Some methods to solve these problems are given. The algorithm has been implemented,and it is ideal.
