土地利用数据库综合中图斑拓扑关系的创建和一致性维护
Creation and Consistency Maintenance of Topological Relationships Between Patches in Landuse Database Generalization
-
摘要: 以LANDUSE DAT文件为例,论述了土地利用地图综合中图斑多边形拓扑关系的特点、数据结构定义及生成方法,阐述了土地数据库综合过程中图斑拓扑关系一致性的维护方法。Abstract: Taking LANDUSE-DAT files as data sources, this paper discusses the features, data structure, and generating methods of topological relationships of between in landuse database generalization, and puts emphasis on the methods for preserving consistency of topological relationships of patches in the process of landuse database generalization.
