Description:
The Moderate Resolution Imaging Spectroradiometer (MODIS) Irrigated Agriculture Dataset for the United States (MIrAD-US) product was produced by the USGS Earth Resources Observation and Science (EROS) Center with funding from the Geographic Analysis and Monitoring program. A primary objective was to identify and map irrigated agricultural areas to factor into drought monitoring investigations. The spatial distribution of irrigated lands across the conterminous United States was mapped for the year 2007 at 250-m spatial resolution. The validation of MIrAD-US is a challenge because no other single source current datasets are available at a national scale for comparison. Thus, this dataset should be considered provisional until a formal accuracy assessment can be completed. The product update is planned for every 5 years, synchronized with the update of the Census of Agriculture by the U.S Department of Agriculture but contingent upon availability of MODIS data and funding.
