Answer to the previous challenge: Brahmaputra River, upstream of Guwahati, India. The two optical satellite images show different water levels in the river linked to seasonal snow melt. The images were captured in October 2020 and April 2021 by the PlanetScope satellite constellation (the individual satellites are called Doves). PlanetScope imagery has a spatial resolution of 3.7 m and the constellation has daily refresh capabilities.
