摘　　要：本文基于大多数点状、线状根图元需依据已存在的线状、面状附属图元自动提取并继承其需要属性的目的,设计了一种能够根据地理实体采集分类标准灵活配置,快速从附属图元批量自动化提取根图元的方法。在iData数据工厂软件上进行自动化生产实验,1 min即可提取大约10万条根图元数据,验证了自动化由附属图元提取根图元的生产效率和准确性。该方法对新型基础测绘图元数据的快速生产工作具有一定的参考意义。This paper aimed to automatically extract and inherit the required attributes of most point,line,and other root elements based on existing affiliated elements such as line and surface.Therefore,the paper designed a method that could achieve flexible configuration according to the geo-entity collection and classification standards and automatically extract root elements in bulk from affiliated elements quickly.Automated production experiments were conducted on iData data factory software,and approximately 100000 pieces of root element data could be extracted in just one minute,verifying the production efficiency and accuracy of automated extraction of root elements from affiliated entities.This method has certain reference significance for the rapid production of new fundamental surveying and mapping element data.
