电子地图数据采集加工系统的设计与实现

Design and Implementation of a System for Collecting & Processing Electronic Maps' Data

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 collecting/positioning is the bottleneck of electronic maps' background processing. This paper proposes, as a solution, a system of collecting & processing electrical maps' data, which integrates map processing and managing. Particularly, it discusses the index optimization method to speed up maps' displaying in building the engine for electronic maps. It also discusses the strategy of database-based point editing as well as automatic generation of organizations' and businesses' geographic co- ordinates.
