Landsat-Derived Global Irrigated-Cropland Product L2 2020 30 m V002

Description

The Landsat-Derived Global Irrigated-Cropland Product Level 2 2020 (LGRIP30_L2_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_L2_IRRI V2 maps agricultural lands by dividing them into irrigated single crop, double crop, and continuous croplands, 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 LGRIP L2 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 single, double, and continuous crop classifications, 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 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. Improvements/Changes from Previous Version There are three major goals in developing LGRIP30 V2: * The goal of LGRIP30 V2 is to overcome uncertainties present in [LGRIP30 V1](https://doi.org/10.5067/community/LGRIP/LGRIP30.001) and increase accuracies and reduce errors of omission and commission, thereby producing the most accurate high-resolution LGRIP30 product for the world. The LGRIP30 V2 is a significantly improved product. For more details see Section 3.1 of the User Guide. * LGRIP30 V2 is for the nominal year 2020; LGRIP30 V1 was for the nominal year 2015. * LGRIP30 V2 introduces Level 1 (L1) and Level 2 (L2) products to provide more detail for irrigated areas (IRRI) and rainfed (RAIN) areas. L1 data provides the greatest detail and classification for irrigated ([LGRIP30_L1_IRRI](https://doi.org/10.5067/Community/LGRIP/LGRIP30_L1_IRRI.002)) and rainfed ([LGRIP30_L1_RAIN](https://doi.org/10.5067/Community/LGRIP/LGRIP30_L1_RAIN.002)) croplands, while L2 data provides aggregated L1 data for irrigated (LGRIP30_L2_IRRI) and rainfed ([LGRIP30_L2_RAIN](https://doi.org/10.5067/Community/LGRIP/LGRIP30_L2_RAIN.002)) areas.
