Data and code for observation-availability-guided Sentinel-1/2 winter wheat mapping in Renshou County

Supporting data, final spatial products, manuscript figures, and selected analysis and figure-generation scripts for a county-scale winter wheat mapping study in Renshou County, Sichuan Province, China. The study integrates Sentinel-1 temporal information with observation-availability-guided Sentinel-2 optical-anchor features, terrain variables, and cropland-confidence information. The repository contains derived tables supporting model ablation, probability-threshold evaluation and area analysis; final winter wheat probability and confidence raster products; figures used in the associated manuscript; and selected scripts used during data analysis and figure preparation. The scientific results and numerical values in this release correspond to the finalized manuscript version and were not recomputed during repository packaging. Original parcel-level field-survey geometries are not distributed because they contain precise field locations and are subject to data-use restrictions. Public Sentinel-1, Sentinel-2, ESA WorldCover, Dynamic World, and DEM source data should be obtained from their original providers or through Google Earth Engine.
