地籍信息系统的设计与实现

THE DESIGN AND ACCOMPLISH OF CADASTRAL INFORMATION SYSTEM

本文讨论了在微机上建立地籍信息系统的技术、方法和途径,提出了适合图形信息管理的关系型拓扑数据结构,以及分解宗地中权属界线图和编辑地籍图形时自动更新其拓扑结构数据的方法。作者综合运用AutoCAD和ORACLE初步建立了一套地籍管理信息系统,具有地籍信息的采集、录入、编辑、修改、查询、变更、统计、分析、输出、安全保密等功能。

This paper discusses the technique, method and way of establishing CIS with micro—computer, introduces and implements the relation—topology data structure which is suited to graphical information management and the method which automatically update topological structure data when decomposing legal boundary of the parcel and editting cadastral elements. A cadastral information management system has been established by means of AutoCAD and ORACLE, which can be used to cottect, input, edit, modify, retrieve, update, count, analyse, output cadastral information and to keep, safety and secret.
