Aksu and Alaer Region means the Aksu Prefecture and Alaer City in the central region of Xinjiang, China. Based on images from Landsat 8, Sentinel-2, and MOD13Q1 acquired in 2020 and the Google Earth Engine (GEE) platform, the authors extracted the cotton planting area (cotton fields) using the random forest method and classification post-processing in the Aksu Prefecture and Alaer City (excluding Wushi and Baicheng due to extremely low cotton planting). The overall classification accuracy of the images in each county was above 0.9, with Kappa coefficients all exceeding 0.8. The dataset includes: (1) distribution of cotton fields with spatial resolution of 250 m; (2) sample point data. This dataset is archived in .tif and .shp formats, and consists of 17 data files with data size of 385 KB (compressed into 1 file with 134 KB).
