摘要
地籍信息时态特征的显著性是其他空间信息所不及的,地籍的生命力和使用价值就在于其现势性和历史与现状的连续性。时态GIS的组织核心是时空数据库,即在空间和时间的参照下组织地理目标数据。因此,建立合适的时空数据库,应用于地籍信息系统中,使其能提供完善的时序分析功能,高效地回答与时间相关的各类问题非常有必要。基于动态多级基态的修正模型能实现时空数据储存、管理和历史回顾的底冗余和高效率。本文就是要结合TGIS和动态多级基态修正模型提出地籍数据库建设的新思路。
The temporal characteristics of cadastral information is more notable than other space information. The life - force and use value of Cadastre is the present situation and the history continuity with current situation. The organization core of temporal GIS is the temporal -spatial database ,which organizes the data of geographical features under the spatial and temporal reference. Therefore, it is very necessary to build the reasonable temporal -spatial database, and apply it into the cadastral information system to provide timing analysis function and solve the various problems related to time. Based on the dynamic multi - level improved model of base state with amendments,it can realize the low redundancy and high efficiency storage, management, and historical review of temporal - spatial data. This paper put forward the new idea on constructing eadastral database combined with TGIS and dynamic multi - level improved model of base state with amendments.
