Geographic Information Systems (GIS) data are crucial for many applications such as disaster response, damage assessment, and recovery efforts. The 2010 Haiti earthquake destroyed buildings where GIS data were stored and many of the relief organizations ultimately depended on data retrieved from outside the country to do their work. The lesson learnt from this experience is that open access data is necessary in assisting tasks in such situations and therefore the evaluation of such data for its quality is important. This research evaluates OpenStreetMap (OSM) data that can be and is used by various organizations. The methodology followed is based on the International Organization for Standardization (ISO) Geographic Information-Quality Principles (ISO19113). According to the ISO19113 standard, the data quality elements are: completeness, logical consistency, positional accuracy, thematic accuracy, and temporal accuracy. The first four elements noted above were tested in this study. OSM data was compared with official data from Abu Dhabi city. Results show that the positional accuracy of OSM data meets the American Society for Photogrammetry and Remote Sensing (ASPRS) standards for 1:20,000-scale maps. This indicates that OSM data could be used for many applications, taking into account the hurdles in GIS data acquisition, cost, availability, licensing, distribution policies, and documentation. The article concludes with a call for incorporation of geospatial data services and data quality initiatives in libraries.

OpenStreetMap(OSM)数据评估:以阿拉伯联合酋长国阿布扎比市为例

地理信息系统(GIS)数据对于灾难响应,损害评估和恢复工作等许多应用至关重要。2010年海地地震摧毁了存储GIS数据的建筑物,许多救援组织最终都依赖从国外获取的数据来开展工作。从这种经验中吸取的教训是,在这种情况下,在协助任务中必须使用开放访问数据,因此评估此类数据的质量非常重要。这项研究评估了各种组织可以使用的OpenStreetMap(OSM)数据。遵循的方法基于国际标准化组织(ISO)地理信息质量原则(ISO19113)。根据ISO19113标准,数据质量要素包括:完整性,逻辑一致性,位置准确性,主题准确性和时间准确性。上面提到的前四个元素已在本研究中进行了测试。OSM数据与阿布扎比市的官方数据进行了比较。结果表明OSM数据的位置精度符合美国摄影测量与遥感学会(ASPRS)的1:20,000比例尺地图标准。这表明,考虑到GIS数据获取,成本,可用性,许可,分发策略和文档方面的障碍,OSM数据可用于许多应用程序。本文最后呼吁将地理空间数据服务和数据质量计划纳入图书馆。OSM数据与阿布扎比市的官方数据进行了比较。结果表明OSM数据的位置精度符合美国摄影测量与遥感学会(ASPRS)的1:20,000比例尺地图标准。这表明,考虑到GIS数据获取,成本,可用性,许可,分发策略和文档方面的障碍,OSM数据可用于许多应用程序。本文最后呼吁将地理空间数据服务和数据质量计划纳入图书馆。OSM数据与阿布扎比市的官方数据进行了比较。结果表明OSM数据的位置精度符合美国摄影测量与遥感学会(ASPRS)的1:20,000比例尺地图标准。这表明,考虑到GIS数据获取,成本,可用性,许可,分发策略和文档方面的障碍,OSM数据可用于许多应用程序。本文最后呼吁将地理空间数据服务和数据质量计划纳入图书馆。成本,可用性,许可,分发策略和文档。本文最后呼吁将地理空间数据服务和数据质量计划纳入图书馆。成本,可用性,许可,分发策略和文档。本文最后呼吁将地理空间数据服务和数据质量计划纳入图书馆。
