Description:
Abstract:
This data layer provides an inventory of active center pivot irrigation systems for the year 2005. Center pivots were identified using multi-date 2005 Landsat 5 satellite imagery and 2005 Farm Service Agency (FSA) Ortho Imagery. The nominal scale is 1:100,000 and the overall accuracy for the irrigation layer was calculated at 93.3%. This project was part of a joint research project with the Nebraska Department of Natural Resources.
Purpose:
Identifying irrigated areas within the Central Platte River Basin provides important information necessary to supplement the hydrologic modeling in the study area. Irrigation data serve a variety of purposes, from water resources planning to land use planning. This data could also be used for watershed analysis and other natural resource management activities.

Process_Description:
Center pivot irrigation systems were identified using 2005 multi-date Landsat 5 satellite imagery and 2005 Farm Service Agency (FSA) Ortho Imagery. Multi-date satellite imagery were collected across the study area to capture spring, summer and fall growing conditions. Center pivots were digitized on screen using ESRI software and were collected across the Cooperative Hydrology Study Area including a one kilometer buffer. Center pivots were checked for accuracy using registered well data points and field data provided by Nebraska Natural Resource Districts and the Nebraska Department of Natural Resources. The overall accuracy for the irrigation layer was calculated at 93.30%. This project was part of a joint research project with the Nebraska Department of Natural Resources
