Sentinel 2A is one of the European Space Agency’s (ESA’s) satellites for the Copernicus program, capable of delivering optical images ranging from visible-near infrared to short-wave infrared. The satellites use 13 spectral bands with resolutions of 10, 20 or 60 meters, and a swath width of 290-km. An identical satellite, Sentinel 2B, is slated to launch in 2016. Together the two satellites will be able to image all of Earth’s landmass in five days.
Copernicus is a joint environmental project between ESA and the European Commission. The satellites primary purposes will be use studying land use and management, soil sealing, forest monitoring, and natural disasters.
