可持续发展科学卫星1号鄱阳湖遥感影像
封面图片是可持续发展科学卫星 1 号(SDGSAT-1)多谱段成像仪于 2021 年 11 月 12 日获取的鄱阳湖彩色合成影像。图像显示鄱阳湖位于枯水期,逐渐出露的湖滨带孕育了繁茂的湿地植被;蝶形湖星罗棋布且呈现不同颜色,体现了水体不同的浑浊程度与营养状况。SDGSAT-1 卫星于 2021 年 11 月 5 日 成功发射,是全球首颗专门服务于联合国 2030 年可持续发展议程的科学卫星,是可持续发展大数据国际研究中心规划的首发星,由中国科学院“地球大数据科学工程”先导专项研制。
SDGSAT-1 satellite image of Poyang Lake
The cover image is a color composite image of Poyang Lake obtained by SDGSAT-1 multispectral imager on November 12, 2021. The image was collected in the dry season, where the exposed floodplain favored the growth of wetland vegetation; various sub-lakes (or butterfly shaped lakes) are dotted with distinct colors, reflecting their different turbidity and trophic status. SDGSAT-1 satellite was successfully launched on November 5, 2021. It is the world's first scientific satellite dedicated to serving the U.N. 2030 Agenda for Sustainable Development. The satellite mission was initiated by the International Research Center of Big Data for Sustainable Development Goals, specially developed by the "Big Earth Data Science Engineering Project" of the Chinese Academy of Sciences.
