| 摘 要： | 自20世纪初地图综合被提出以来,经过几十年的完善和发展,逐步实现了由完全手工作业模式向计算机自动化综合模式的转变,然而当前自动化水平仍比较有限。本文结合地图学理论和符号几何特征设计规范,建立了由模型基元和贝塞尔曲线构成的统一表达地理模型,辅之以NIV空间关系模型,提出了模型实体化的拓扑补偿和模型地图化的制图补偿自动化实现方法,探索一条解决地图自动综合这一世界性难题的方法与思路。最后展望了地图自动综合的前景以及下一步努力的方向。

| Abstract: | Since the concept was proposed at the beginning of last century, cartography generalization has been gradually changed from full manual operation mode to computer automation mode after decades of improvement and development. However, the level of map automation is still relatively low until now. So, this paper puts forward an integrated representation of geographical model for entity and symbol on the basic of innovative model units and spatial relation model. Then the automatic methods of topological compensation for model entity and cartography compensation for model symbolization are established, we want to explore a solution to solve the worldwide problem of automatic cartography generalization. Finally, this paper look into the future and developmental direction of automatic cartography generalization. |
