2026-09-15 Corn Yield per Unit Area Dataset for Core Demonstration Zone Farmland (2022–2025) doi:10.57760/sciencedb.iga.0017m en This dataset provides gridded maize yield retrieval products for Nong'an County and the Chenjiadian core demonstration area in Jilin Province from 2022 to 2025. Maize yield is defined as production per unit area, and the dataset is intended to characterize the spatial distribution and interannual variation of maize yield at both the core demonstration area and county scales. The data are organized by year and include: (1) maize yield products for the core demonstration area retrieved from UAV multispectral data; and (2) maize yield products for Nong'an County retrieved from Sentinel-2 remote sensing data. The data are provided in GeoTIFF (.tif) format and can be directly used in GIS and remote sensing software for overlay analysis, statistical aggregation, and cartographic visualization. Information such as the raster coordinate system, spatial resolution, NoData value, and value range should be determined based on the metadata of each GeoTIFF file. corn; yield; Multispectral PUBLIC https://creativecommons.org/licenses/by/4.0/ dataset Science Data Bank
