摘要
利用ArcGIS平台完成1:80万吉林省地震构造图绘制工作,由此表述专业图件的一般绘制过程与主要技术手段。对其项目的一般绘制过程,包括组织实施方式、原始资料规范化、图件的专业分层做简要说明。对绘制过程中的技术难点、技术手段,如:地理信息数据库的建立、数据导入、图像矢量化、空间归并、符号化等关键技术,做深入探讨。文中介绍了使用全新的GIS理念绘制吉林省地震构造图的方法和关键技术手段。
1 ： 800 000 seismotectonic map of Jilin has been drawn using ArcGIS. Through the work, the general drawing process and main technical means of professional map is illustrated in this paper. The general drawing process includes the methods of organizing and implemen- ting, standardization of source material, and brief illustration of special layers. Technical difficulty and means in drawing process, such as founding geographic information database, importing data, vectorizing maps, merging spaces and symbolizing, are discussed. The brand-new GIS ideas is introduced, with which seismotectonie map of Jilin is made.
