摘要
境外地理空间信息数据在获取手段上受到诸多限制,获取到的数据质量参差不齐。因此,最大限度地利用好收集到的数据资料,并对其进行集成与融合是境外地理空间数据收集的重要任务。对目前网络上能够公开收集到的2种全球矢量数据DAE和VMAP1进行分析,并针对数据的特点设计了数据融合的处理方法。为拓展境外地理空间信息数据的集成与融合手段提供参考。
The geographical spatial information data of overseas is limited in data acquisition,the quality of the acquired data seems varies. Therefore,make the most of the collected data and carries on the integration and fusion is an important task of overseas geographical spatial data collection. The paper selects two kinds of the global vector data to analyze： DAE and VMAP1,which can only collected publicly at present. After all,the paper designs the processing method of data fusion according to the characteristics of the data,which can provide reference to expand the methods of overseas geographical spatial information data integration and fusion.
