基于规则的多源空间数据集成处理

Multi-source Spatial Data Integration Based on Rule

现有空间数据集成在实现时依赖专家参与且功能较为固定。在阐述多源空间数据集成的基础上,抽取隐含在专家经验中的规则,并通过合适的方法分别从外部、内部进行表示。最终将规则表示成计算机能够识别、存储、使用的形式,实现规则和程序代码相分离。在用户需求和空间数据确定的前提下,模拟专家完成数据集成处理,便于广大普通用户的使用,提高了代码重用性且易于维护。

Existing methods of spatial data integration rely heavily on expert’s participation and the function is fixed.Based on the multi-source spatial data integration,this study forms the rule from expert’s experience,and represents it by suitable external and internal forms.Then the rule can be identified,stored and managed by computer,and also separated from procedure code.With certain users’ demands and spatial data,this method can simulate expert to accomplish data integration.The application effect shows the spatial data integration based on rule is reliable,and it’s also accessible for common users,good for code reuse,and easy to maintenance.
