Abstract & Keywords
Abstract: Byusing domestic remote sensing data such as domestic GF-1 B/C, GF-2 and GF-6 from 2018 to 2019, and adopting value-added processing methods of satellite data such as image registration, block adjustment, geometric orthorectification, image fusion, and image mosaic, we obtained a high-resolution mosaic image of a large area in the Beijing-Tianjin-Hebei urban agglomeration with a spatial resolution of 2 m. This dataset has few clouds, balanced color, and geometric accuracy of about 1–2 pixels (2–4 m). 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 urban agglomeration
