摘　　要：地矿测绘数据因其空间性强、数据量大、类型复杂和时间动态性等特点,在矿产资源勘查与开发中尤为关键,其中,地理信息系统(GIS)对地矿测绘数据集成与决策支持具有重要意义。通过集成地理空间数据、属性数据和分析功能,GIS提供了强大的决策支持工具。本文探讨了GIS在数据预处理、空间数据融合和空间数据库构建中的关键技术与方法,并通过实例分析展示了GIS在矿产资源评价、三维模型展示等决策支持中的应用效果。研究表明,GIS技术能够有效提高地矿测绘数据的质量和查询效率,为矿产资源开发提供科学依据。Geological surveying and mapping data is particularly crucial in the exploration and development of mineral resources due to its characteristics such as strong spatiality,large volume,complex types and temporal dynamics.Among them,the Geographic Information System(GIS)is of great significance for the data integration and decision support of geological surveying and mapping.By integrating geospatial data,attribute data,and analytical functions,GIS provides powerful decision support tools.This study explores the key technologies and methods of GIS in data preprocessing,spatial data fusion,and spatial database construction,and demonstrates the application effects of GIS in decision supports such as mineral resource evaluation and 3D model visualization through case analysis.The research shows that GIS technology can effectively improve the data quality and query efficiency of geological surveying and mapping,providing scientific basis for the development of mineral resources.
