Where farmland is irrigated worldwide, raw stage (30 m)

Landsat-Derived Global Irrigated-Cropland Product L1 2020 30 m V002
land NASA LPCLOUD Level 1 GeoTIFF
In plain English

What it measures. A 30 m map identifying where cropland is irrigated, sorted into 32 irrigated-crop types, along with non-irrigated land and water bodies, plus an accuracy assessment.

How it's made. Produced from Landsat 8 satellite imagery spanning 2019-2021 to represent the year 2020; this is the Level 1 (raw/early) stage of the product.

How & where you'd use it. Aimed at food and water security questions like where and how much land is irrigated. Coverage currently spans only the continental US, with the rest of the world to be added later.

Official description

The Landsat-Derived Global Irrigated-Cropland Product Level 1 2020 (LGRIP30_L1_IRRI) 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_L1_IRRI V2 maps agricultural lands by dividing them into 32 irrigated cropland types and calculates applicable cropland 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 L1 V2 Irrigated 30 m resolution GeoTIFF file contains a layer that identifies areas of irrigated cropland (cropland that had at least one irrigation during the crop growing period) divided into 32 types, non-irrigated land (rainfed cropland and areas not classified as 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 contain data only for the conterminous United States (CONUS). LGRIP30 V2 data covering the rest of the globe will be added at a later date.
