US_WindTurbines_USGS

This layer contains the locations of utility-scale wind turbine generators in Texas. This point file is intended for multi-scale thematic mapping and analysis.

            

              

                

                  

                    The spatial data were obtained from the United States Geological Survey and are current as of 2013. The wind turbine locations originated from the US FAA Digital Obstacle File. The attributes were modified to include site name, on year, county, FAA information, and a variety of turbine specs and location information. The coordinate system of this data is WGS 1984.
                  
                  

                    “This data set provides industrial-scale onshore wind turbine locations in the state of Texas through July 22, 2013, corresponding facility information, and turbine technical specifications. The original database has more than 47,000 wind turbine records that have been collected, digitized, locationally verified, and internally quality controlled. Turbines from the Federal Aviation Administration Digital Obstacle File, through product release date July 22, 2013, were used as the primary source of turbine data points. Verification of the turbine positions was done by visual interpretation using high-resolution aerial imagery in ESRI ArcGIS Desktop. Turbines without Federal Aviation Administration Obstacle Repository System numbers were visually identified and point locations were added to the collection. We estimated a locational error of plus or minus 10 meters for turbine locations. Wind farm facility names were identified from publically 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 for turbines were assigned based on the wind turbine make and model as described in literature, specifications listed in the Federal Aviation Administration Digital Obstacle File, and information on the turbine manufacturer’s website. Some facility and turbine information on make and model did not exist or was difficult to obtain. Thus, uncertainty may exist for certain turbine specifications. That uncertainty was rated and a confidence was recorded for both location and attribution data quality.” - USGS
