Sentinel-2 - Data Products - Sentinel Handbook
Sentinel-2 products available for users (either generated by the ground segment or by the Sentinel-2 Toolbox) are listed in the product types table.
|Name||High-Level Description||Production & Distribution||Data Volume|
|Level-1C||Top-Of-Atmosphere reflectances in cartographic geometry||Systematic generation and online distribution||⁓600MB (each 100km x 100km2)|
|Level-2A||Bottom-Of-Atmosphere reflectances in cartographic geometry||Systematic and on-user side (using Sentinel-2 Toolbox)||⁓800MB (each 100km x 100km2)|
Products are a compilation of elementary granules of fixed size, along with a single orbit. A granule is the minimum indivisible partition of a product (containing all possible spectral bands).
For Level-1C and Level-2A, the granules, also called tiles, are 100x100 km2 ortho-images in UTM/WGS84 projection. Download the Sentinel-2 tiling grid kml.
The UTM (Universal Transverse Mercator) system divides the Earth's surface into 60 zones. Each UTM zone has a vertical width of 6° of longitude and horizontal width of 8° of latitude.
