基于数据库驱动的地质图快速制图技术研究

地质图应用广泛,在国民经济建设中发挥着十分重要的作用。本文分析了地质图在应急使用中存在的困难,对面向国家基础地质图数据库的快速制图关键技术进行了分析研究。以国家基础地质图数据库为数据源,经过一系列的数据整合操作,通过ArcGIS平台,实现地质图数据的快速提取,并对地质图信息进行符号化,最终输出专题应急地质图件。地质图的快速制作输出,可以很好的提高制图效率,满足不同用户对海量数据快速和自动处理的要求。

Study on the technique of rapid geological mapping based on the database drive

Geological maps are widely used and play a very important role in national economic construction. This paper analyzes the difficulties in the emergency use of the geological map and studies the key techniques of rapid mapping to the national base geological map database. With the national basic geological map database as the data source, through a series of data integration operations, through ArcGIS platform, the rapid extraction of geological map data, and the symbol of geological map information, finally output thematic emergency geological map. Rapid output of geological maps can improve the efficiency of mapping and meet the requirement of rapid and automatic processing of massive data by different users.
