摘　　要：地质图是地质调查和地质成果公开展示的基础,标准地图是地质图件编制必不可少的参考底图。为了解决标准化地质制图中的地图投影、比例尺难统一与数据格式不一致问题,本文以中国1∶1200万地质图标准化制图为例,运用ArcGIS和Adobe Illustrator软件,加工处理最匹配标准地图比例尺的地质图数据,确定了地质图和标准地图数据套合后边界平均偏移距离最小、要素匹配度最高的Albers投影最佳参数,并处理要素间的关系,实现了2组地图数据的适配。在地质图标准化和规范化的基础上,编制了基于标准地图的地质图。本文基于标准地图的地质数据加工处理、整合、制图技术流程具有较强的适用性,为公开版标准化地质图件制作提供参考。Geological map is the basis for geological survey and achievements demonstration to the public.Standard map is the necessary reference base map for geological mapping.In order to solve the incompatibility problems of map projection,scale and data format in standard geological mapping,applying ArcGIS and Adobe Illustrator software,this study takes the 1∶12 million geological mapping as an example and processes the geological map data that best matches the standard map scale.The best parameter of Albers projection has been defined according to the minimum boundary offset distance and the highest matching rate of the features after the integration of geological map and standard map,and the relations of features have been processed to realize the data matching of standard map and geological map.This study ensures the accuracy and standardization of the geological map based on the standard map.The technology of geological data process,integration and mapping based on standard map is applicability and provides a reference to produce the public version of the geological map.
