Hyperspectral pseudo-color image of lake in Gongzhuco Plateau, Tibetan Plateau by "Xiamen Science andTechnology-1" satellite
The cover image shows a hyperspectral pseudo-color depiction of Gongzhu Co Lake, located in Xizang. It was captured by the "Xiamen Science and Technology-1" satellite on August 30, 2023. Gongzhu Co Lake serves as the first high-altitude lake encountered when entering the Ngari Prefecture region via the southern route. The lake is surrounded by pristine mountain ranges from the Himalayas and Gangdise mountains, showing clearly visible mountains and textures, and the edge of the lake blend seamlessly with the natural pastures. The satellite's hyperspectral imaging camera operates within the visible-near-infrared band. It utilizes grating spectrometry, CMOS array detectors, and FPGA-based digital video compression technology. The fused data achieves a maximum ground resolution of 10 m, encompasses 150 spectral channels, and covers a swath width of 80 km. The camera's key attributes include its compact size, wide spectral range, expansive field of view, and significant relative aperture. These features enable it to meet diverse user requirements, such as high spectral resolution, medium-high spatial resolution, and the fusion of multi-source remote sensing data. The "Xiamen Science and Technology-1" satellite was successfully launched on January 9, 2023. Customized for urban application services in Xiamen, this hyperspectral satellite finds primary usage in various domains, including marine economy, natural resources, meteorology, emergency management, and smart cities. It consistently provides sustainable, high-precision remote sensing images and application services,effectively addressing the demands of commercial remote sensing and data applications across multiple sectors.
