This data set was compiled in support of the manuscript entitled “A Geographical Survey of Center Pivot Irrigation Systems in the Central and Southern High Plains Aquifer Region of the United States” submitted to the Applied Engineering in Agriculture journal. This polygon data set represents all center pivots in the Central and Southern High Plains (Ogallala) Aquifer of the United States, where rapid groundwater depletion is threatening the future of irrigated agriculture. Specifically, this data set provides detailed information on the number, area, and spatial distribution of center pivot systems. The World Imagery base map available through the ArcGIS (version 10.8.0, Esri, CA, USA) was used as the reference for manual digitization of center pivots across the study area. The World Imagery base map includes imagery obtained by GeoEye-1 and WorldView-2, -3 and -4 satellite sensors at 0.3‒0.5 m spatial resolution, which made the center pivots and their components (i.e. pivot point, main pipe, wheal tracks, and swing arms) discernible. Our data set will potentially provide valuable and highly accurate information for many field-level applications, including but not limited to studying irrigation uniformity and its dynamics during the season, developing variable rate irrigation prescriptions, improved watershed hydrologic and environmental simulations, and irrigation energy requirement and greenhouse gas emission estimations across the study area.
