Description:
Abstract:
This data layer provides an inventory of active center pivot irrigation systems for the year 1982.  Center pivots were identified and delineated using multi-date 1982 Landsat 3 Multi-Spectral Scanner(MSS) satellite imagery.
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_Step:
Process_Description:
Center pivot irrigation areas were identified using multi-date 1982 Landsat 3 MSS satellite 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 COHYST study area including a one kilometer buffer.  Center pivots were checked for accuracy using registered irrigation well data current to 1982, land cover data provided by the Nebraska Natural Resources Conservation Service(NRCS) and the Nebraska Department of Natural Resources(NDNR). 1993 digital orthophotography were used to help determine field boundaries.
