摘要:

信息技术快速发展，数字找矿工作不断创新，数字地质的信息化程度不断提高。依据地质空间数据特性，使用合适的技术方法进行数据库建设，提高地质空间数据的科学性和可靠性。通过介绍运用通用软件MAPGIS和专用软件GEOMAG实施山东省成矿地质背景专题属性数据库的建设流程、建设方法和质量监控。探讨在地质背景底图类图层文件出现特殊情况时，根据属性数据特征，所应采取的有效处理方法。

Abstract:

Accompanying with rapid development of information technology, digital prospecting work has been innovated, and the informatization degree of digital geology has been improved continuously. According to the characteristics of geospatial data, appropriate technical methods have been used in database construction in order to improve the scientificity and reliability of geospatial data. In this paper, the construction process, construction method and quality monitoring under the metallogenic geological background in Shandong province have been introduced by using general software MAPGIS and special software GEOMAG. Effective processing methods according to the characteristics of attribute data when there are special cases in the layer files of geological background base map have been discussed.
