A group of researchers from different universities and government groups have published a study of how Landsat’s free and open data policy has benefitted users of the programs satellite imagery products.
The Landsat series of satellites has been imaging the Earth’s surface for nearly 50 years, providing vital imagery for a range of purposes from the natural sciences to civil administration and conflict monitoring. NASA and the USGS recently announced that the next iteration of the program, Landsat 9, is due to launch in 2020.
Satellite imagery from Landsat 8 has been used by a Belgian marine research institute to detect shallow water shipwrecks. Satellite imagery from Landsat 8 can detect the concentration of sand and silt particles in the ocean, which can then be used to pinpoint a potential shipwreck location.
