The legacy version of the USGS wind project database was updated through 2014 and is incorporated into the USWTDB.ĪCP releases quarterly reports tracking utility-scale U.S. None of the data in the USWTDB are field verified. The uncertainties associated with location and attribute data quality are rated, and a confidence level is recorded. Because some make and model information does not exist or is difficult to obtain, uncertainty may exist for certain turbine specifications. Technical specifications for turbines are assigned based on turbine make and model as described in literature, specifications listed in the FAA DOF, and collected via ACP, LBNL, and turbine manufacturer websites. Moreover, because of a lag in obtaining up-to-date aerial imagery, some turbine locations have not been visually verified.

Visual verification also enables identification and removal of duplicate turbine points and decommissioned turbines from the database, although some decommissioned turbines likely have not yet been identified and thus remain in the data set. The USWTDB is updated as frequently as quarterly as new data become available and will lag installations by approximately one quarter.Īll turbine points in the data set are visually verified using high-resolution aerial imagery in ESRI ArcGIS Desktop, and X/Y locations are manually moved to the base of the turbine with an estimated locational tolerance of 10 meters. The USWTDB combines a 2014 USGS data set (48,956 wind turbines, including decommissioned and duplicate turbines) with a 2017 LBNL data set (43,827 wind turbines) and includes regular updates from ACP’s WindIQ as well as the Federal Aviation Administration (FAA) Digital Obstacle File (DOF) and Obstacle Evaluation Airport Airspace Analysis (OE-AAA). They are not as fast as cached maps, but have built-in capabilities that allow clients to dynamically change the layer's behavior and appearance. Dynamic USWTDB Service: Dynamic map services are drawn at the time they are requested by a user.The USWTDB cached map service allows find, identify, and query tasks to reach the underlying data. When viewing a cached service, users will be viewing static pictures of the USWTDB and will be limited in dynamic functionality like filtering and data-driven styling. Cached USWTDB Service: Cached map services use a set of pre-created images to quickly serve maps over the web or via applications that support map services.USWTDB web services can be consumed by GIS applications that support ArcGIS map services or OGC Web Map Service (WMS) specifications. However, users who wish to consume the USWTDB web service can do so by using the RESTful service endpoints below.

Note that XML files can be read in any text editor.

Users are encouraged to download the metadata file for detailed information about the USWTDB. Metadata is the background information which describes the content, quality, condition, and other appropriate characteristics of the data. The CSV (comma-separated values) format is common non-proprietary format for storing tabular data stored as plain text. It is based on JSON (JavaScript Object Notation) and plays an important role in many spatial databases, web APIs, and open data platforms. GeoJSON is an open standard format designed for representing simple geographical features, along with their non-spatial attributes. It is a (mostly) open specification for data interoperability among GIS software products. The geometry for a feature is stored as a shape comprising a set of vector coordinates. A shapefile stores non-topological geometry and attribute information for the spatial features in a data set. The shapefile format is a popular geospatial vector data format compatible with a variety of GIS software.
