Abstract

In the paper, the main method we discuss and improve relates to the snake model, which is used to displace the roads and resolve the conflict. A snake is an energy-minimizing spline guided by internal constraint forces and influenced by external enforcement. In the paper, the theory of snake model is illustrated in detail. Then, according to the demand of cartography, the snake model is improved as follows. First, the relationship between the parameters of snake and shape character of road is built up in order to keep the shape of displaced road better. Second, the propagation extent of external force in snake model is controlled to keep the accuracy of road position. Third, the power attribute of intersection point between roads is set to control the displacement of the intersection point and keep the topological relationship of roads. At last, the general thought of disposing the spatial conflict of road networks are brought forward by using the improved snake model. One experiment research is made in terms of the general thought, which represents that the roads are displaced and the spatial conflicts are solved well.
