摘要
管线要素是国家基础地理信息数据的重要组成部分。50000动态更新项目采用基于影像进行地物要素更新的方法。由于管线要素在影像上不易判读,外业核实工作量大,因此,需结合生产实际对管线要素中输电线要素的更新方法进行总结分析。
Pipeline elements is an important component of national fundamental geographic information date.Update feature elements of 50,000 dynamic update project is based on images.It need to analysis summary update method of electric-power line elements in pipeline combining actual production for the cause of which is hard to identify based on the images,and it has a heavy workload in field verification task.
