一种分等级的双时态时空数据模型

Introduction of A Kind of Hierarchical Bi-temporal Spatiotemporal Database Model

在分析了宗地要素的时间与空间特征的基础上,提出了一种支持分等级的双时态理论的时空数据模型,该模型采用双向链接边表结构来描述宗地要素的空间属性,能较好地支持时间查询和空间查询。

Based on analysis of the spatiotempora l characteristics of the parcel land,a kind of spatiotemporal database model supporting the hierarchical bitemporal theory is put forward in the paper,which uses the structure of doublylinked list to describe spatial characteristics of the parcel land and could support relatively well the time and space inquiry.
