摘　　要：本文旨在借助AutoCAD环境进行二次开发实现在城镇地籍数据库建设前期的数据整理。在数据库拓扑检查过程中,图形经常会产生多余节点,比如地籍数据库中的宗地及界址线等在拓扑过程中产生多余节点(除界址线的首末两个节点外,其它都是多余的),这是不合理的。项目的主要任务是:利用AutoCAD软件环境进行基于VB.NET的开发,在不影响数据精度及拓扑关系的情况下去除AutoCAD图形中多余的节点,再导入数据库中使用。Abstract This paper aims to use the AutoCAD environment to achieve the second development in the pre-construction data Cadastral database collation. Topology of the inspection process in the database, graphics, often produce excess nodes, such as cadastral parcel in the database and the boundary lines in the process of generating extra node toplogy （except for boundary line of the first and last two nodes, the other is redundant a）, is unreasonable. The project＇s main tasks are： the use of AutoCAD software environment based on VB. NET development, eliminate redundant nodes in the AutoCAD drawing, without compromising data accuracy and topology of the cases, and then import the database to use.
