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 100×100 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.
