The image is a composite, blending natural-color imagery of water with a false-color image of the land. While it could be considered a work of art, there are some useful aspects to looking at the land this way! You can easily distinguish areas of live vegetation (green) from land that is bare or contains dead vegetation (light brown) or the network of sediment-rich rivers and ponded flood water (dark brown).

Our Landsat Program has been monitoring Earth from space since 1972, providing decision-makers from across the globe free data to better understand environmental change, manage agricultural practices, allocate scarce water resources, respond to natural disasters, and more.
