2026-03-19 High resolution optical satellite remote sensing image cultivated land sample dataset in Yanhe River Basin (2022-2023) doi:10.57760/sciencedb.j00001.01452 en This dataset is based on high-resolution optical remote sensing images (GF-2). It generates a sample dataset of cultivated land in the Yan River Basin through a combination of manual visual interpretation and deep learning algorithms. The dataset includes single-band grayscale image (panchromatic) samples, multi-band RGB (multispectral) true color (3,2,1) composite image samples, and multi-band RGB true color composite fusion image samples (panchromatic images and multispectral images). The resolutions are 4m,2m, and 2m, respectively, with a resolution size of 256x256. The dataset comprises manually annotated samples and enhanced samples, totaling 3000 samples, with a data volume of approximately 648 MB. The data formats are *.tif, *.twf, and *.txt. The dataset consists of 3 data folders, including: (1) multispectral samples (Sample 1), with a sample size of 1000 and a data volume of 307 MB; (2) panchromatic samples (Sample 2), with a sample size of 1000 and a data volume of 66 MB; (3) fusion image samples (Sample 3), with a sample size of 1000 and a data volume of 275 MB.逐句对照 High resolution 2 satellite image; Yanhe River basin; multispectral; panchromatic; Blend images Shi Lei Wang Kun Yang Liangyan He Lirong Fan Hongjian Xia Liheng PUBLIC https://creativecommons.org/licenses/by-nc/4.0/ dataset http://www.doi.org/10.11922/11-6035.csd.2025.0084.zh Science Data Bank
