基于边-节点和原子属性的多比例尺GIS数据模型

Multi-scale GIS Data Model Based on Edge-Node and Atom Attribute

    摘要
  • 摘要: 针对当前多比例尺GIS存在的数据冗余问题,提出并实现了一种基于边节点和原子属性的数据模型,在模型中较好地解决了复合属性问题,并讨论了该模型在实际应用中的适应性和可扩展性。

     

    Abstract: In multi-scale GIS, the redundancy of data is ineluctable. A relation data model based on meta model is presented to reduce the redundancy effectively. The problem of composite attribute is solved in this model. The validity and feasibility of the data model is discussed.
