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-1B granules are small images in sensor geometry sensed by each single of the twelve MSI detectors and are 23x25 Km2 large. For Level-1C and Level-2A, the granules, also called tiles, are 110x110 km2 ortho-images in UTM/WGS84 projection. Earth is subdivided on a predefined set of tiles, defined in UTM/WGS84 projection and using a 100 km step. However, each tile has a surface of 110x110km² in order to provide large overlap with the neighbouring.
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.
