电子政务中空间数据的转化集成方法研究

The Process of Transformation and Integration Method for Spatial Data in E-government Systems

针对目前电子政务中空间数据集成分析功能研究不足的现状,提出一种有效的空间数据转化集成方法,将地理空间数据、非空间属性数据、空间谓词数据以及电子政务事务数据进行集成,构成面向政务分析的更为全面的数据源。在此基础上,设计多维空间数据模型来集成这些数据源。突破现有GIS查询分析功能,支撑更为复杂的空间数据与非空间数据联动查询的模式。

Due to the lack of the integration and analytic function for spatial data in current E -government systems,the article proposes an effective method for transforming spatial data, and integrates digital map, non - spatial attributes, spatial predicates and transaction data in E - government together. Then a multi - dimensions model for integrating spatial data is proposed to realize the transformation of spatial data,which can enrich the analytic functions for E - government.
