2021年海南区域高分一号GF1_WFV遥感影像数据集

GF-1卫星是中国高分辨率对地观测系统的第一颗卫星，于2013年4月26日12时13分04秒由长征二号丁运载火箭成功发射，开启了中国对地观测的新时代。GF-1卫星搭载了两台2m分辨率全色/8m分辨率多光谱相机，四台16m分辨率多光谱相机。卫星工程突破了高空间分辨率、多光谱与高时间分辨率结合的光学遥感技术，多载荷图像拼接融合技术，高精度高稳定度姿态控制技术，5年至8年寿命高可靠卫星技术，高分辨率数据处理与应用等关键技术，对于推动我国卫星工程水平的提升，提高我国高分辨率数据自给率，具有重大战略意义。

The Gaofen-1 (GF-1) satellite is the first satellite of China's High-Resolution Earth Observation System. It was successfully launched by a Long March-2D carrier rocket at 12:13:04 on April 26, 2013, opening a new era for China's Earth observation. The GF-1 satellite is equipped with two 2m-resolution panchromatic/8m-resolution multispectral cameras and four 16m-resolution multispectral cameras. The satellite project has made breakthroughs in key technologies including optical remote sensing technology combining high spatial resolution, multispectral and high temporal resolution, multi-load image stitching and fusion technology, high-precision and high-stability attitude control technology, high-reliability satellite technology with a service life of 5 to 8 years, and high-resolution data processing and application technologies. This is of great strategic significance for promoting the improvement of China's satellite engineering level and increasing the self-sufficiency rate of China's high-resolution data.
