摘要
论文结合国内外的研究成果,吸收面向对象的思想和方法,利用统一建模语言UML,完成了面向对象数字地质图数据模型的建立。从制图学的角度出发,设计了数字地质图数据的概念模型、逻辑模型,定义了构成数字地质图各要素间的逻辑关系,并简要叙述了物理模型的实现平台和建立过程。面向对象的数字地质图数据模型打破了关系模型范式的限制,更加合理地将空间数据和属性数据有效地融合在一起,为数字地质图的高效存储、管理、分析、应用、可视化表达提供一种科学、合理、可靠、可操作性强的机制和模式,作为一种尝试和探索,具体的设计和实施还有待于进一步研究。
The author,combining domestic and international research results of digital geological map,absorbing object-oriented thoughts and methods,utilizes Unified Modeling Language（UML） to finish the building of an object-oriented digital geological map data model.From the view of cartography,the author, designs concept model and logical model of object-oriented digital geological map data model,defines logical relationships of interrelationship between the features of the model,and then briefly describes implement platform and process of physics model.Object-oriented data model for digital geological map,breaks normal forms of relational model ,more reasonably and effectively integrate spatial data and attribute data,and provide a scientific,logical,reliable,operable machine-made and mode for efficient storage,management,analysis,application,visualization expression of digital geological map.This model only is an attempt and discussion,and particular design and implement is to be researched bv further experiments.
