基于动态多级基态的修正模型的TGIS研究
摘 要
针对基于基态修正模型的时态地理信息系统(TGIS)历史回顾效率低下的问题,提出了一种基于动态多级基态的修正模型(DMBSA),并结合TGIS的典型应用——土地产权产籍管理信息系统,依据地籍数据的时空内聚性及空间、属性内聚性强度,通过分析面向对象的时空数据特点,设计了DMBSA模型的时空数据库,实现了对地籍变更的历史回顾;最后对基于上述模型和方法自主开发的土地产权产籍管理信息系统REGIS进行了介绍。应用结果表明,基于动态多级基态的修正模型(DMBSA)能低冗余、高效率地实现时空数据的存储、管理和历史回顾。

A Study on TGIS Based on Dynamic Multilevel Base State with Amendments
() Abstract
It is inefficient that realizing the query and redivivus of the history information based on the modal of base state with amendments though the modal can store change data with low redundancy. Based on the character of spatio-temporal cohesion and the spatio-property's, this paper introduces a method for designing and building spatio-temporal database based on dynamic multilevel base state with amendments, through analyzing the parcel land change character of the object-oriented TGIS. The modal of based on dynamic multilevel base state with amendments (DMBSA) is derived from the modal of base state with amendments and conquer the shortcoming of the modal. At last, a self-developed software package of land cadastral information system (ReGIS) based on above model and methods is presented. The application - ReGIS states that the modal of based on dynamic multilevel base state with amendments (DMBSA)can store and manage spatio-temporal data with low redundancy and trace history information efficiently.
