摘要
本文以地理信息系统在小比例尺区域地质编图中的应用为基础,结合《亚洲中部及邻区系列地质图》的编制,详细阐述了应用ArcInfo、MapGis等GIS软件进行数字地质编图的方法。对地理空间数据和专业地质空间数据的编制做了详细介绍,其中包括各种要素制图综合、属性库制作、编码设计、现势资料的补充等。根据数据源的不同,制定了不同的技术路线和工作方法。将来自不同国家的数据源进行数据转换、投影变换和误差校正,转换为统一的数据格式和投影坐标系统。对基于GIS的区域地质编图方法及数据源做了具体分析。
Based on the application of GIS （Geographic map production, combined with the production of the Information System） and in small-scale regional geological Geological Map Series of Central Asia and Adjacent Areas, the paper expounds the methods of digital geological map production based on the GIS softwares such as Arcinfo and Mapgis and introduces the compilation of geographical and geological spatial data, including map-making generalization, attribute database production and code design of various elements, as well as supplements of new materials. According to different data sources, different technical lines and map production methods are lain down. The data from the data sources of different countries are converted into the unifying data format and projection coordinates system by data conversion, projection conversion and error correction. A concrete analysis has been made of the methods of regional geological map production based on the GIS and data sources.
