It includes: a manifest.safe file which holds the general product information in XML. a preview image in JPEG2000 format. subfolders for measurement datasets including image data (granules/tiles) in GML-JPEG2000 format.
Which is the best JP2 image for Sentinel 2?
You can simply use the TCI.jp2 file that its included in the SAFE.zip files. Note that these files are not available in S2 files before October 2016 -scale 0 4096 is a reasonable value for Sentinel-2 scenes and afaik also used for the TCI.jp2 images.
What is the purpose of the Sentinel 2 mission?
Sentinel-2 is an observation mission developed by the European Space Agency to monitor the surface of the Earth official website . Sets of images are taken of the surface where each image corresponds to a specific wavelength.
Which is the best scale for Sentinel 2?

What can Sentinel 2 imagery be used for?
Sentinel 2 imagery is of value in a range of applications including forestry, agriculture, land resource management and environmental monitoring. This is exciting news since the Sentinel 2 data compliments Landsat data accessible through ArcGIS Online.
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.

How to calculate reflectance of water in Sentinel 2?
We will explore the reflectance proprieties of water in the Green and NIR bands, B3 and B8 in the Sentinel 2 case (McFeeters 1996): NDWI (McFeeters) = (Green-NIR) / (Green+NIR).
What is the swath width of Sentinel 2?
The swath width of Sentinel-2 is 290 km. In comparison, the swath width of LANDSAT 5 TM and LANDSAT 7 ETM+ is 185 km, and the swath width of SPOT-5 is 120 km. This features makes Sentinel 2 perfect for a wide range of applications.
