Since 1990’s a new generation of satellite sensors with powerful capabilities have been launched to collect massive amounts of data about our planet and the many changes it has experienced.There are dozens of remote sensing satellites orbiting the Earth collecting invaluable information about the Earth’s surface, oceans and the atmosphere and how they interact. Satellite images have been collected for scientific and technical purposes as well as just appreciating its simple beauty. These satellites collect information that our eyes cannot, collections from 30M to 0.5M resolution is now available.
