The Moderate Resolution Imaging Spectroradiometer (MODIS) Irrigated Agriculture Dataset for the United States (MIrAD-US) suite of irrigation products was developed by the U.S. Geological Survey (USGS) Earth Resources Observation and Science (EROS) Center.

The goal of MIrAD is to provide a comprehensive and consistently processed geospatial dataset for irrigated agriculture across the conterminous U.S. (CONUS). MIrAD Version 4 offers irrigation datasets for 2002, 2007, 2012, and 2017 at 250-m and 1-km spatial resolutions.

 

We have employed a geospatial modeling approach and implemented it for four time periods (2002, 2007, 2012, and 2017) to consistently map irrigated agriculture across the conterminous U.S. These data can be used to help assess water-quality trends in ground and surface waters, explain drought impacts on vegetation, and support the application and refinement of current water volumes used for irrigation.

 

The method incorporated the following three primary data inputs:

  1. USDA county-level irrigation irrigated area statistics (https://www.nass.usda.gov/AgCensus/index.php)

  2. Annual peak Normalized Difference Vegetation Index (NDVI) derived from Collection 6 Aqua MODIS imagery (https://aqua.nasa.gov/modis)

  3. A land cover mask for agricultural lands derived from NLCD (https://www.mrlc.gov/)

 

A detailed description of the input data and methodology is provided by Pervez and Brown (2010).

Merging remote sensing data and national agricultural statistics to model change in irrigated agriculture

Over 22 million hectares (ha) of U.S. croplands are irrigated. Irrigation is an intensified agricultural land use that increases crop yields and the practice affects water and energy cycles at, above, and below the land surface. Until recently, there has been a scarcity of geospatially detailed information about irrigation that is comprehensive, consistent, and timely to support studies tying agri

Mapping irrigated lands at 250-m scale by merging MODIS data and National Agricultural Statistics

Accurate geospatial information on the extent of irrigated land improves our understanding of agricultural water use, local land surface processes, conservation or depletion of water resources, and components of the hydrologic budget. We have developed a method in a geospatial modeling framework that assimilates irrigation statistics with remotely sensed parameters describing vegetation growth con

Mapping irrigated lands across the United States using MODIS satellite imagery

This book opens a new pathway for global mapping that is focused on a specific land use theme, such as irrigated or rain-fed croplands and classes within these themes. Since croplands use most of the water consumed by humans, specific knowledge of irrigated and rain-fed croplands will be critical for precise estimates of water use. At present and in the coming decades, irrigated and rain-fed cropl
