How does Sentinel 2 work?
The Sentinel-2 mission consists of two satellites developed to support vegetation, land cover, and environmental monitoring. The Sentinel-2 MultiSpectral Instrument (MSI) acquires 13 spectral bands ranging from Visible and Near-Infrared (VNIR) to Shortwave Infrared (SWIR) wavelengths along a 290-km orbital swath.
What is Sentinel 2 MSI?
SENTINEL-2 is a wide-swath, high-resolution, multi-spectral imaging mission, supporting Copernicus Land Monitoring studies, including the monitoring of vegetation, soil and water cover, as well as observation of inland waterways and coastal areas.
How do I remove cloud from satellite imagery?
Methods of Removing Cloud Cover from Satellite Imagery [2] A more common approach today is using pixel sorting, where multiple images are utilized and images are selected that are not too dark (e.g., shadowing) or bright (i.e., cloud cover).
How big are the bands of Sentinel 2?
There are 13 Sentinel 2 bands in total. Each band is 10, 20 or 60 meters in pixel size. Sentinel 2 consists of 2 satellites. First came Sentinel 2A which was launched in 2015. Next came Sentinel 2b in 2017. Two additional satellites (Sentinel 2C and 2D) are planned to launch in 2020 and 2021. This will make a total of four Sentinel-2 satellites.
What is the purpose of the Sentinel-2 format?
GML provides the encoding necessary for georeferencing the image. Sentinel-2 data are intended for scientific use within a Geographic Information System (GIS) or other special application software that supports the GMLJP2 format.
What are the names of the Sentinel 2 satellites?
Sentinel 2 consists of 2 satellites. First came Sentinel 2A which was launched in 2015. Next came Sentinel 2b in 2017. Two additional satellites (Sentinel 2C and 2D) are planned to launch in 2020 and 2021. This will make a total of four Sentinel-2 satellites.
Where can I find the USGS Sentinel 2 collection?
EarthExplorer , USGS Global Visualization Viewer (GloVis), or the Sentinel2Look Viewer can be used to search, preview, and download Sentinel-2 data. The collection is located under the Sentinel category in EarthExplorer. The current USGS Sentinel-2 archive is only a partial representation of all available acquisitions from ESA.
