Rainfed versus irrigated farmland, 2020 (30 m)

Landsat-derived Global Rainfed and Irrigated-Cropland Product L3 2020 30 m V002
land NASA LPCLOUD Level 3 GeoTIFF
In plain English

What it measures. A detailed map sorting farmland into two types: fields watered only by rainfall versus fields that get at least one round of irrigation during the growing season. Each square covers about 30 meters on the ground, and the map also flags non-cropland and water bodies.

How it's made. Built from a stack of Landsat 8 images taken between 2019 and 2021 to represent the year 2020, then processed into classified GeoTIFF map tiles.

How & where you'd use it. Helps with food and water planning, like estimating how much cropland depends on irrigation versus rain. Note: this version currently covers only the continental United States, with the rest of the world planned for later.

Official description

The Landsat-derived Global Rainfed and Irrigated-Cropland Product Level 3 2020 (LGRIP30_L3) Version 2 data provides high-resolution, 30 meter (m) cropland data to assist and address food and water security issues of the twenty-first century. As an extension of the Global Food Security-support Analysis Data ([GFSAD](https://www.usgs.gov/centers/western-geographic-science-center/science/global-food-security-support-analysis-data-30-m)) project, LGRIP L3 V2 maps agricultural croplands by dividing them into irrigated and rainfed croplands, and calculates irrigated and rainfed areas across the globe. LGRIP data are produced using Landsat 8 time-series satellite sensor data for the 2019 through 2021 time period to create a nominal 2020 product. Each LGRIP30 L3 V2 30 m resolution GeoTIFF file contains a layer that identifies areas of rainfed cropland (cropland areas that are purely dependent on direct precipitation without any artificial watering), irrigated cropland (cropland that had at least one irrigation during the crop growing period), non-cropland, and water bodies over a 10° by 10° area, as well as an accuracy assessment of the product. A low-resolution browse image is also included. Currently, LGRIP30 V2 products only contain data for the conterminous United States (CONUS). LGRIP30 V2 data covering the rest of the globe will be added at a later date.
