Reflecting the growing use of Earth observation, a software toolbox that provide users with the tools they need to process satellite data has been downloaded more than 500 000 times in less than five years. The ESA Sentinel Applications Platform, or SNAP for short, is a free and open toolbox for processing data products from numerous satellite missions such as Copernicus Sentinel-1, Sentinel-2 and Sentinel-3, as well as ESA’s SMOS mission, and ‘Third Party Missions’ where ESA uses its multimission ground systems to acquire, process, distribute and archive data from satellites owned by other organisations.
