Onshore Industrial Wind Turbine Locations for the United States to March 2014

This data set provides industrial-scale onshore wind turbine locations, corresponding facility information, and turbine technical specifications, in the United States to March 2014. The database has nearly 49,000 wind turbine records that have been collected, digitized, locationally verified, and internally quality assured and quality controlled. Turbines from the Federal Aviation Administration Digital Obstacle File, product date March 2, 2014, were used as the primary source of turbine data points. Verification of the position of turbines was done by visual interpretation using high-resolution aerial imagery in ESRI ArcGIS Desktop. Turbines without Federal Aviation Administration Obstacle Repository System (FAA ORS) numbers were visually identified and supplemental points were added to the collection. A locational error of plus or minus 10 meters for turbine positions was estimated. Wind farm facility names were identified from publicly available facility data sets. Facility names were then used in a web search of additional industry publications and press releases to attribute additional turbine information (such as manufacturer, model, and technical specifications of wind turbines). Wind farm facility location data from various wind and energy industry sources were used to search for and digitize turbines not in existing databases. Technical specifications assigned to were based on the make and model as described in literature, in the Federal Aviation Administration Digital Obstacle File, and information from the turbine manufacturers' websites. Some facility and turbine information did not exist or was difficult to obtain. Thus, uncertainty may be present. That uncertainty was rated and a confidence was recorded for both location and attribution data quality.本数据集提供了截至2014年3月的美国境内工业级陆上风力涡轮机点位、对应风电场设施信息以及涡轮机技术规格参数。该数据库共收录近49000台风力涡轮机记录，所有记录均经过采集、数字化处理、点位核验以及内部质量保证与质量控制流程。本数据集的涡轮机核心数据源自2014年3月2日发布的美国联邦航空管理局数字障碍物文件（Federal Aviation Administration Digital Obstacle File）。涡轮机位置核验采用ESRI ArcGIS Desktop软件结合高分辨率航空影像进行目视解译完成。对于未拥有美国联邦航空管理局障碍物存储系统（Federal Aviation Administration Obstacle Repository System, FAA ORS）编号的涡轮机，研究人员通过目视识别完成点位标注，并将补充后的点位纳入数据集。经估算，涡轮机点位的位置误差范围为±10米。风电场设施名称源自公开可用的行业数据集。随后，研究人员通过网络搜索相关行业出版物与新闻稿，结合设施名称补充涡轮机的额外信息，如制造商、机型以及涡轮机技术规格参数。研究人员还从各类风电与能源行业数据源获取风电场设施点位数据，用于检索并数字化收录现有数据库未覆盖的涡轮机记录。分配给各涡轮机的技术规格参数基于公开文献、美国联邦航空管理局数字障碍物文件以及涡轮机制造商官网披露的信息确定。部分设施与涡轮机信息存在缺失或难以获取的情况，因此数据集可能存在不确定性。针对该不确定性已进行评级，并对点位数据与属性数据的质量分别记录了置信度。
