中文摘要： 在地图自动综合中需要解决地图要素空间冲突问题，对地图自动综合整个过程进行控制。图形综合方法和移位方法是解决地图要素空间冲突问题的主要途径。由于空间目标移位的传递效应，有时会形成新的空间冲突区域；有时单独使用空间目标移位方法或图形综合方法无法完全处理空间冲突问题。因此，为了解决地图综合过程中的地理空间冲突问题，就需要强调空间目标移位方法和图形综合方法之间的协同。本项目的主要研究内容是：建立不同空间冲突类型与已有地图要素移位算法之间的对应关系，并分析不同空间冲突类型与解决该类冲突的图形综合操作以及移位操作之间的对应关系；研究空间目标群移位方法和图形综合方法之间的协同机制，基于空间关系约束和地图制图知识，构建它们的智能化协同模型；依据地图要素类型和空间冲突类型，建立基于图形综合协同的地理空间目标移位的智能化算法。本项目的研究成果能提高地图要素空间冲突处理的效率和地图自动综合的智能化水平。

英文摘要： The problem of space conflict between map objects needs to be resolved during the map automated generalization, and this whole process also needs to be evaluated and controlled. Methods of graphic generalization and map objects displacement are the main approaches for removing space conflicts. New space conflicts may be formed due to the propagation of spatial objects movement, and space conflict problems cannot be solved completely only through displacing spatial objects or merely generalizing graphs. Therefore, for the purpose of resolving space conflicts in map generalization effectively,a collaboration method emphasizing the cooperation of object displacement and graphic generalization is required now. The main content of this project is as follows. The corresponding relationships between various types of space conflicts and existing displacement algorithms will be established, and the corresponding relationships between different kinds of space conflicts and operation methods containing displacement and graphic generalization to resolve such class conflict will be analyzed. The collaborative mechanism between displacement methods of spatial objects cluster and graphic generalization will be researched, and their intelligent collaboration model based on constrains of spatial relations and cartographic knowledge will be built. According to the types of cartographic features and space conflicts, intelligent displacement algorithms of geo-spatial objects will be built up based on collaborating graphic generalization. The research result of this project can be used to improve the efficiency of solving space conflicts of cartographic features and intelligent level of map automated generalization.
