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.
Where can I find the Sentinel-2 tiling grid?
The Sentinel-2 tiling grid is referenced to the U.S. Military Grid Reference System (MGRS). Tiles can be fully or partially covered by image data. Partially covered tiles correspond to those at the edge of the swath. The download package from the USGS includes one file for each of the 13 spectral bands plus metadata.
What are the spectral bands of the Sentinel 2?
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.
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.
When was the second Sentinel 2 satellite launched?
A second identical satellite (Sentinel-2B) was launched March 7, 2017 and is operational with data acquisitions available on EarthExplorer. Together they cover all Earth’s land surfaces, large islands, and inland and coastal waters every five days.
What are the features of the USGS sentinel2look viewer?
The USGS Sentinel2Look Viewer allows comprehensive searching and downloading of full-resolution Sentinel-2 images. Features include temporal comparison functionality, export customizable graphic file, generate and download a video animation of the oldest and newest images displayed in the viewer, to name a few.
How do I open the Sentinel 2 file?
Sentinel-2 data can be opened directly in Focus using the relevant XML (S2*.xml) or manifest.safe file. The band selector window will open. Sentinel-2 is delivered with three spatial resolution options.
How big is the Sentinel 2 image size?
The data even includes rasters for sun azimuth and elevation, which are needed for calculation of reflectance: The images are of great quality and, at 10 m pixel size, the views are really impressive: Two sections of a Sentinel 2A scene of the Vesuvius area, Bay of naples, Italy, acquired on 2016-01-24.
How do I merge my Sentinel 2 imagery?
In the Data Merge tool click Browse and then navigate to the location of your Sentinel-2 imagery. Make sure that both the 10m and 20m bands are loaded. In the Step 2 window click Browse and choose and Output File name. In the Step 3 window make sure that all of the required bands are listed.
