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

    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.
