Abstract: In order to solve the problem of multi-scale GIS display, this paper proposes a multi-scale GIS display method based on topological operator. The method computes topological operator based on label, verdicts and merges the spatial relationship of geometric, expresses and displays the multi-scale of spatial data. Experimental results prove that this method can not produce data missing, and verdict the feasibility and validity of this method.

Key words: Geography Information System(GIS), spatial topological operator, multi-scale

摘要: 为了解决多尺度GIS数据显示的问题,提出基于拓扑算子的多尺度GIS显示方法。该方法建立基于标签的空间拓扑算子的计算,进行几何体空间关系的判断与合并,实现空间数据的多比例尺表达与显示。实验结果验证该方法的可行性和有效性,并证明其不会产生数据损失。
