This resource is a repository of the map products for the Annual Irrigation Maps - High Plains Aquifer (AIM-HPA) dataset produced from Landsat satellite data in Deines et al. 2019. The maps cover a 608,260 km2 area across the High Plains Aquifer in the United States. AIM-HPA provides annual irrigation maps for 34 years (1984-2017). Please see Deines et al. 2019 for full details. If needed, copies can be requested from the author at email@example.com.

Disclaimer: Irrigation maps are produced for research purposes and have an associated classification accuracy estimated to be ~91%. Overall, they are able to capture about 85% of the variation in county irrigated area statistics provided by USDA NASS. Please see Deines et al. 2019 for further detail on the methods underlying map production and estimated accuracies across years.
AIM-HPA can also be accessed directly from Google Earth Engine via the following publicly shared asset ID: "projects/h2yo/IrrigationMaps/AIM/AIM-HPA/AIM-HPA_Deines_etal_RSE_v01_1984-2017"
Example: var aimhpa = ee.Image("projects/h2yo/IrrigationMaps/AIM/AIM-HPA/AIM-HPA_Deines_etal_RSE_v01_1984-2017");
