数据采集和地址定位是电子地图后台加工处理中的瓶颈问题。本文提出了通过实现电子地图数据采集加工系统将整个地图的加工和维护过程融为一体的解决方案。着重讨论了在构造电子地图引擎中使用的二级优化提高显示速度的方法，基于数据库的卢、位编辑和企事业单位地理坐标自动生成的策略。 Data acquisition and address positioning are bottlenecks in the processing of background maps of electronic maps. This paper presents a solution to the process of integrating the processing and maintenance of the entire map by implementing the electronic map data acquisition and processing system. This paper focuses on the methods of improving the display speed of the second-level optimization used in the construction of the electronic map engine, the database-based editing and the automatic generation of geographical coordinates of enterprises and institutions.
