地籍数据库动态更新机制的探讨

地籍管理信息系统的建设目标和发展趋势使得它必须要求地籍数据库中的数据具有现势性,包括空间数据以及非空间数据,最大限度反映城市地籍权属现状、提供全面综合、准确的地籍数据。随着现代社会发展脚步的不断加快,土地变更也越来越频繁,更加突显了地籍信息系统数据库建设中动态机制的重要性。本文以张家界市地籍建库项目为平台,以建库过程中对于地籍数据更新处理的技术方案为依托,概述了在这个工程中所采用的地籍数据更新的动态机制。满足了数据获取与更新体系中建立高效、高精度的数据采集和更新系统的要求,保证了系统数据库中的数据能够得到及时的更新。

The discussions on dynamic update in cadastral data-base

Several requirements are needed for cadastre database according to the goal and development tendency of cadastre management information system,such as currency of spatial and non-spatial data,reflection of cadastre authority situation at most,provision of comprehensive and precise cadastre data.With the rapid development of modern society,the land changes frequently,which reveals the importance of dynamic mechanism for cadastre information system database construction.Taking Zhangjiajie Cadastre database as a platform,the dynamic mechanism of cadastre data update is summarized based on update technology.It shows that the dynamic mechanism can satisfy the demand of high efficiency and precision of data acquision and update.
