Description:
Abstract:
This data layer provides an inventory of active center pivot irrigation systems in Nebraska for the 2005 growing season. Center pivots were identified using multi-date 2005 Landsat 5 satellite imagery and 2005 Farm Service Agency (FSA) Ortho Imagery. This project is part of a joint research project with the Nebraska Department of Natural Resources.
Purpose:
Identifying irrigated areas provides important information necessary to supplement the hydrologic modeling in Nebraska. 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.

2005 NAIP Ortho Imagery
Process_Step:
Process_Description:
Center pivot irrigation systems in Nebraska 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. Center pivots were checked for accuracy using registered irrigation well data points and field data provided by Nebraska Natural Resource Districts and the Nebraska Department of Natural Resources. This project was part of a joint research project with the Nebraska Department of Natural Resources. More information and data products are available at http://calmit.unl.edu/2005landuse/.
