摘要
地籍信息具有显著的时间特性,将地籍数据的时间、空间及属性三者合理地组织在地籍信息系统中的研究具有重要意义。本文借鉴目前TGIS和各种时空应用模型的优势,提出一种基于宗地变更的时空数据结构。针对地籍管理系统中宗地变更和历史回溯的需求,将数据库分为历史库和变更库,比较好的实现了宗地管理要求,有效弥补了一些时空数据库过于臃肿、系统运行效率低下等缺陷。
Temporality is the distinct attribute of cadastral information. It is very important to scientifically and efficiently manage three kinds of data that exist in the Cadastral Information System, such as spatial data, temporal data and attributive data. Based on the research of TGIS and the advantages of existing spatio-temporal database model, this paper proposes a design of a spatiotemporal cadastral database which is divided into historical database and alterative database. This design fulfills the requirements for management of cadastral data and reduces data redundance and enhances the efficiency of database.
