| 摘 要： | 在完成全国黄金遥感数据库项目工作实践中提出作用归一化方法，将面向目标分析１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。

| Abstract: | 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. |
