摘要

结合编制矿产资源专题图,探讨了基于GIS的矿产专题地图的设计流程以及制作方法;针对ArcGIS自带符号库不能满足专业需要的现状,重点研究了矿产资源类型符号库的设计与实现方法,并通过绘制徐州市矿产资源分布图进行了验证.%Mineral resources thematic map provides intuitive and accurate information for mineral department leaders. In order to fully demonstrate the results of the mineral resources survey and monitoring project, it is of great significance to produce high-quality thematic maps of mineral resources. Combined with the practice of mineral resources thematic maps production, this paper discussed the process and key issues of mineral thematic map production using GIS technology. Since the symbol library of ArcGIS can't meet the professional demands, the design and realization methods of mineral resource symbol library were also researched.
