道路网数据是导航电子地图的骨架数据,为保证数据的现势性,导航数据生产部门需要参考不同来源的道路数据进行更新,本文针对该种现状和需求,提出了数据匹配、数据抽取、数据整合的路网数据融合技术方法,并以郑州地区为试验,进行了验证,具有重要的理论意义与现实意义。
Road network data is tile foundation of navigation electronic map. In order to keep the ctlrrency of data, navigation data production department must update road data aecording to different sources of road data frequently. This paper put forward some technologies for data matching, data choosing, and data fusion. Then, taking Zhengzhou area as an example, some tests arc made for validating these technologies. A conclusion can be draw, these technologies have theoretic and realistic meaning.
