NASA GFSAD Project

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) 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 ...基于陆地卫星（Landsat）衍生的2020年全球灌溉农田一级产品（LGRIP30_L1_IRRI）版本2数据集，提供分辨率为30米的高精度农田数据，用于助力并解决21世纪的粮食与水安全问题。作为全球粮食安全支持分析数据（Global Food Security-support Analysis Data, GFSAD）项目的延伸成果，LGRIP_L1_IRRI V2将农业用地划分为32种灌溉农田类型以绘制农业用地分布图，并计算全球范围内的对应农田面积。LGRIP数据集基于2019至2021年的陆地卫星8号（Landsat 8）时间序列卫星传感器数据生成，以构建标称……
