基于加权图的地籍时空数据描述模型研究

Spatio-Temporal Data Model in Cadastral Information System Based on Weighted Graph

摘要: 以计算机通用的数据结构———图为基础,研究了基于加权图的时空数据组织策略,为表达时空语义提供了一种形式化的描述方法,并分析了以该模型为中间件实现不同时空模型转换的应用前景。

Abstract: A new spatio-temporal data model based on graph theory is presented,the organizing strategy of spatio-temporal data based on weighted graph is studied,and a formalized method to describe spatio-temporal semanteme is provided.The application foreground of transformation between different spatio-temporal data models is analyzed with the model.
