京津冀城市群大区域高分卫星数据产品

A large-region high-resolution satellite dataset of Beijing-Tianjin-Hebei Urban Agglomeration

采用2018–2019年的国产高分一号B/C、高分二号、高分六号等卫星遥感数据,通过影像配准、平差、几何校正、影像融合、影像镶嵌等卫星数据深加工处理方法得到京津冀城市群地区大区域高分辨率镶嵌影像,空间分辨率为2 m,是针对京津冀城市群研制的现势性较好的高分卫星即得即用数据产品。本数据集云量少、色彩均衡、几何精度约为1–2像素(即2–4 m)。影像数据包含可见光及近红外波段,可为京津冀城市群的土地利用、城市发展、生态环境监测等方面的研究及应用提供数据支撑。

By using 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.
