2026-08-31 XDA28100504 - Thematic Maps of Cultivated Land Quality Evaluation doi:10.57760/sciencedb.iga.001d7 en This dataset contains multiple core raster datasets for cultivated land quality evaluation covering the entire Youyi Farm. Specifically, it includes seven types of thematic raster data with a 10-meter resolution: aspect, surface roughness, average normalized difference vegetation index (NDVI) during the growing season, NDVI in the litterfall period, standard deviation of vegetation index, and slope. All files are stored in GeoTIFF raster format. The dataset has a unified spatial resolution of 10 meters and fully covers the whole area of Youyi Farm. It serves as fundamental core data to support comprehensive regional cultivated land quality evaluation, crop growth monitoring, and analysis of site conditions of cultivated land. The data accuracy meets the requirements of refined research and evaluation of cultivated land resources at county and farm scales.
