基于地学G^4I系统的元数据分类方法

Metadata Classification Method Based on Geosciences G^4I System

以实现空间数据的标准化为前提,对空间数据库中元数据管理系统的作用和分类原则进行了探讨,指出了传统的分类方法对于以矿产资源预测为目标的地学系统而言存在着弊端。需要结合矿产资源预测的特点,对空间数据库建设中元数据的分类原则进行补充,提出了面向客户应用即按矿产资源预测目标进行分类,实现对空间数据查询的高效利用。该方法可以在地学G4I系统中得以实施和应用。

The authors discuss about the effects and classification principles of metadata manage system in spatial databases with premise of spatial databases standardization and points out the disadvantages of conventional classifying methods for geosciences G(4)I system with the target of mineral resources prediction.Combining characteristics of mineral resources prediction,it supplements the classifying principles of metadata in spatial databases establishment and poses a customer oriented application which makes ...
