What is Sentinel-1 used for?
The Sentinel-1 mission facilitates services that include monitoring of Arctic sea-ice extent, routine sea-ice mapping, surveillance of the marine environment (including oil-spill monitoring and ship detection for maritime security), monitoring land-surface for motion risks, mapping for forest, water and soil management ...
What is the difference between Sentinel-1 and Sentinel-2?
The first Sentinel-1 satellite was launched in April 2014. The objective of Sentinel-2 is land monitoring, and the mission will be composed of two polar-orbiting satellites providing high-resolution optical imagery. Vegetation, soil and coastal areas are among the monitoring objectives.
