“海丝二号”小卫星密西西比河入海口遥感影像
封面为“海丝二号”小卫星于2023 年 2月12日拍摄的密西西比河入海口水域遥感影像,图中棕色到绿色、蓝色的清晰变化反映了密西比河河水与墨西哥湾海水的递次混合,进而刻画多层次、动态、多变的水质,进一步反映了海丝二号“多光谱小卫星其20m分辨率和高信噪比的优势。”海丝二号自2021年6月11日成功发射以来,已拍摄了全球近海、湖泊超10亿平方公里的观测数据,其多光谱遥感图像为观测、研究近海、湖泊水环境生态系统提供了宝贵的数据支撑。"海丝二号"数据免费共享,可通过网址http://101.34.79/查询并提交数据请求。
Mississippi River mouth imaged by HiSea-2 SmallSat
The cover image was collected by HiSea-2 on February 12.2023 overthe Mississippi River delta region. The changes of color from brown to green and blue indicate dynamic variations of water quality, which represent the mixing of Missisippi River water with oceanic water of the Gulf of Mexico, and further reflect the advantages of 20 m spatial resolution and high signal-to-noise ratio offered by HiSea-2 multi-band SmallSat. Since her successful launch on June 11,2021, HiSea-2 has collected over 1 billion square kilometers of data over global nearshore waters and inland lakes. The multi-band image data is an important source for monitoring and studying the aquatic ecosystem of nearshore and lake environments. Data of HiSea-2 are freely sharable, users may visit http://101.34.254.79/ to find interested image data.
