What sensor is on the Sentinel-2?
What sensor is on the Sentinel-2?
Sentinel-2 will carry an optical payload with visible, near infrared and shortwave infrared sensors comprising 13 spectral bands: 4 bands at 10 m, 6 bands at 20 m and 3 bands at 60 m spatial resolution (the latter is dedicated to atmospheric corrections and cloud screening), with a swath width of 290 km.
Is Sentinel-2 an active sensor?
The availability of new Earth Observation products, for example Sentinel-1 (active) and Sentinel-2 (passive) imageries, with both high spatial and temporal resolution, have the potential to facilitate flood detection and monitoring of surface waters changes which are very dynamic in space and time.
What does Sentinel-2 mean?
Sentinel-2 is an Earth observation mission from the Copernicus Programme that systematically acquires optical imagery at high spatial resolution (10 m to 60 m) over land and coastal waters.
What is Sentinel-2 satellite used for?
As well as monitoring plant growth, Sentinel-2 can be used to map changes in land cover and to monitor the world’s forests. It also provides information on pollution in lakes and coastal waters. Images of floods, volcanic eruptions and landslides contribute to disaster mapping and help humanitarian relief efforts.
What is the difference between Sentinel-1 and Sentinel-2?
Sentinel Missions 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.
Is Sentinel-2 optical?
SENTINEL-2 carries an optical instrument payload that samples 13 spectral bands: four bands at 10 m, six bands at 20 m and three bands at 60 m spatial resolution. The orbital swath width is 290 km.
Does Sentinel-2 has thermal band?
Sentinel 2 has not consist of any thermal band while Landsat-8 have it (band 10 and 11). ASTER is also consist of the 5 Thermal bands (resolution is of 90 meters and resampled upto 15 meters).
Can Sentinel-2 see through clouds?
The cloud-free Sentinel-2 images have been selected with a threshold of 10% cloud coverage, while cloudy images are within 20% and 70% of cloud coverage. The Sentinel-2 data is from the Level-1C top-of-atmosphere reflectance product and has values in the range [0, 10,000]. All 13 original bands were included.
Does Sentinel-2 have thermal band?
Is Sentinel-2A SAR?
The European Space Agency’s ( ESA ) sentinel constellation is a recent satellite that consists of the Sentinel-1 ( S1 ) and Sentinel-2 ( S2 ) earth observation instruments. Both sensors disseminate freely available multispectral optical ( S2 ) and multi-polarised SAR ( S1 ) data.
Is Sentinel-2A lidar?
Lidar surveys and Sentinel-2 satellites are used to map shallow bathymetry. The capabilities of SDB for recursive mapping at 10 m resolution are evaluated. The composited SDB model allows monitoring over environments with transient turbidity. Detection change is identified at two dynamic inlets in North Carolina (USA).
