| 摘 要： | 针对地理国情普查成果制图的实际需求,提出了一种顾及图斑原有拓扑关系的化简方法。通过对图斑数据进行拓扑构建,将对图斑的化简转化为对共享弧段的化简;同时对弧段进行分类,对不同类型的弧段采用相应的化简方法。通过实例验证表明,该方法能够保持图斑化简前的形态结构,并保持图面整洁,符合地图制图要求,取得了较好的应用效果。

| Abstract: | According to the actual demand for the mapping of geographical conditions census, this paper proposes a simplified method considering the original topological relations of the patches.By constructing the topography of the patches, the simplification of the patches is transformed into the simplification of the shared arc which is classified.The corresponding simplified methods are used for different types of arcs.The results show that the method can maintain the structure of the patches and keep the map clean and tidy.The method conforms to the requirements of map mapping, which obtains the good application effect. |
