Sentinel-2 Tile Mask

The Copernicus Sentinel-2 mission is based on a constellation of three identical satellites in the same orbit. Each satellite carries an innovative wide swath high-resolution multispectral imager with 13 spectral bands for a new perspective of our land and vegetation.

Sentinel-2 is the result of close collaboration between ESA, the European Commission, industry, service providers and data users. The mission has been designed and built by a consortium of around 60 companies led by Airbus Defence and Space, and supported by the CNES French space agency to optimise image quality and by the DLR German Aerospace Centre to improve data recovery using optical communications. Sentinel-2A was launched on 23 June 2015, followed by Sentinel-2B on 7 March 2017. On 5 September 2024, Sentinel-2C was launched into orbit to join its siblings and ensure the continuous provision of high-resolution data from the mission. The constellation ensures a revisit time of 5 days from a 2-satellite constellation at equator and systematically covers land and coastal areas between 84°North and 84° South. With its multispectral imager and wide swath coverage, the Sentinel-2 mission not only offers continuity, but also expands on the French Spot and US Landsat missions.

A wide range of products and applications are based on Sentinel-2 L1C and/or L2A images. From this platform, you could visit the Theia Sentinel-2 Surface Water-based or Theia Sentinel-2 Snow Cover-based and also Theia Sentinel-2 Water Quality-based collections that are based on Sentinel-2 tiles. This collection offers the set of elementary granules of Sentinel-2-based products.

For Level-1C and Level-2A, the granules, also called tiles, are 110 km x 110 km ortho-images projected onto the Universal Transversal Mercator (UTM) spatial reference system, which divides Earth into 60 longitudinal zones. Each UTM zone has a vertical width of 6° of longitude and horizontal width of 8° of latitude. 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 110 km x 110 km in order to provide large overlap with the neighbouring.
