Sentinel-1, which consists of two state-of-the art satellites, provides continuous radar images from every part of the globe, mapping Europe every three days and the entire world once every 12 days. This provides continuous mapping of forest health, vegetation, biomass, soil types, land use change, sustainable agriculture and water resources. As the radar can penetrate any cloud cover, data is guaranteed to be available, irrespective of poor conditions, and enables bespoke data collection over smaller areas.
