摘　　要：基于CAD的矢量地形数据是一类基本的重要的基础地理数据,其应用十分广泛,同时也是各类地理信息系统重要的数据源,其属性精度、逻辑一致性是其重要质量元素,本文论述了基于AuotoCAD二次开发实现矢量地形数据计算机自动化高效检查的技术方法。CADbased vector terrain data is an important foundation of the basic geographical data, its application is wide. At the same time, it is also an important data source of geographic information system, its important quality elements are attribute accuracy and logical consistency. This paper discusses the techniques and methods of computer automation efficient inspection of the vector terrain data through the second development of AutoCAD-based.
