A large-region high-resolution satellite dataset of Beijing-Tianjin-Hebei Metropolitan Region

Using domestic remote sensing data such as domestic GF-1 B/C, GF-2 and GF-6 from 2018 to 2019, and with value-added processing of satellite data such as image registration, block adjustment, geometric orthorectification, image fusion, and image mosaic, a high-resolution mosaic image of a large area in the Beijing-Tianjin-Hebei urban Metropolitan Region was obtained with a spatial resolution of 2m. This data set is of few clouds, balanced color, and geometric accuracy of about 1-2 pixels (2-4m). The image data includes visible light and near-infrared bands, which can provide data support for the research and application of land use, urban development, and ecological environment monitoring in the Beijing-Tianjin-Hebei Metropolitan Region.
