摘要
在完成全国黄金遥感数据库项目工作实践中提出使用归一化方法 ,将面向目标分析、关系密切的地质要素进行数据融合处理 ,建立面向地质成矿分析集属性、几何、拓扑关系于一体的数据模型 ,从而大大方便了不同要素间空间位置的查询和检索 ,利于多源数据复合分析 ,克服了以往的专题分层模型实体间相互割裂的缺陷。
The digital generalization model, which is developed during finishing the project of national ore remote sensing database is presented in this paper.The functions of this model include as following: the object-oriented analysis,the geological element integrating and the mineralization analysis. This model uses the unique entity-relation to handle the geometry and theme data . Because of the these functions, the analysis of complex spatial operation becomes easy and the defects of slow and complex analysis of geological theme layer model are overcome.
