摘要
为了提高地质编图中的地质体合并效率,本文研究了地质体同属性或相似属性合并的原理,提出了一种基于地质专家知识的自动化的同属性合并方法,基于ArcGIS Engine组件编程实现了融合空间和属性数据的合并模块.使用真实生产数据对软件功能测试结果表明,该模块可将一个图层中属性值相同或相近的两个以上地质体自动合并成一个新的大地质体,结果与手工操作效果相同,但效率可提升上千倍,已应用于中国地质调查局编图试点工作中.
In order to improve the efficiency of merging geological bodies in geological mapping,this paper studies the principle of merging geological bodies with the same attribute or similar attributes,proposes an automated same-attribute merging method based on the knowledge of geologists,and realizes a merged module of spatial and attribute data fusion based on ArcGIS Engine component programming.Testing with real production data shows that the module can automatically merge two or more geological bodies with the same or similar attribute values in a layer of mapping into a new large geological body,with the merger effect being as good as by manual operation but the efficiency being raised by thousands of times.The merging method has been applied to the pilot mapping work of China Geological Survey.
