摘要
自发地理信息的迅速发展逐渐成为了地学领域的研究热点,研究分析了自发地理信息应用于地图制图更新中面临的数据质量评价、几何数据融合与属性信息匹配转换等核心问题,在此基础上提出了自发地理信息分析与融合处理的一般流程,并针对每个问题分别提出了相应的解决策略;最后,利用北京地区OSM数据,对流程和策略进行了验证。
The rapid development of volunteered geographic information generally becomes research focus in the field of geoscience.This paper analyzes the core questions of the evaluation of data quality,the fusion of geometric data and the conversion and matching of attribute information.during the volunteered geographic information used in mapping update,then proposes a general process of volunteered geographic information analysis and fusion operation,and finally puts forward the corresponding solutions for each question.Finally,the process and the strategy was verified by using Beijing OSM data.
