GSC Sentinel-2 PDGS OCD Issue 1 Revision 2 (draft) - 25.07.2010 GMES-GSEG-EOPG-TN-09-0008 page 96 of 350 4.4 Data Products This section provides a comprehensive view over the Sentinel-2 mission data-products that will be delivered by the PDGS. The baseline choice of Sentinel-2 data products and their characteristics presented here has been motivated mostly by an analysis of the GMES service requirements extrapolated from the DAP-R and from the Sentinel-2 MRD provided in Appendix-A. 4.4.1 PRODUCT PORTFOLIO The detailed Sentinel-2 product list and characteristics are provided in the GSC Sentinel-2 PDGS Products Definition Document [RD-07]. Table 4-2 outlines the Sentinel-2 product list and main characteristics of each product. A mapping to the “Optical Processing Level” labelling used in the DAP-R is provided for reference. Product- Type Identifier DAP Optical Processing Level Outline Description S2HKTM N/A Sentinel-2 spacecraft Housekeeping telemetry in TF format S2MSI0 0 MSI raw-image-data (compressed) in raw ISP format S2MSI1A L1A MSI uncompressed raw image data in sensor geometry with spectral bands coarsely co-registered and appended Ancillary data S2MSI1B L1B Radiometrically-corrected (calibrated) MSI image data in sensor geometry with spectral bands coarsely co-registered and refined geometric model appended but not applied S2MSI1C L1B orthorectified Ortho-rectified and UTM geo-coded Top-of-Atmosphere Reflectance with sub-pixel multi-spectral and multi-date registration Intended Users FOS MSI instrument experts PDGS internal users Expert users General users Acquisition Coverage (all systematic) Global at every orbit + All land surfaces between 56 South latitude and 84 North latitude; + major islands (greater than 100 km2 size), EU islands and all the other small islands located at less than 20km from the coastline; + Mediterranean Sea, all inland water bodies and all closed seas; + Specific acquisition campaigns as required through the HLOP. Cf. section 4.5.4.1.1 Table 4-2 Sentinel-2 Product list and product main characteristics In addition, a prototype Level-2A product hereafter referred to as the S2MSI2Ap will provide Bottom-of-Atmosphere multi-spectral reflectance in the S2MSI1C geometry (orthorectified & ESA UNCLASSIFIED – For Official Use © ESA The copyright of this document is the property of ESA.

The generation of this prototype product will be triggered interactively by the PDGS users based on S2MSI1C products. Product Granules or Tiles: All MSI products will aggregate one or several “granules” of fixed size. In this respect, the product granularity corresponds to the minimum indivisible partition of one Sentinel-2 product. The products are always split per orbit, i.e. granules corresponding to distinct orbits are never compiled within the same product. Table 4-3 summarises the product granularity associated to each type of product. Product-Type Identifier Granularity S2HKTM One entire downlink pass (downlink dependent) S2MSI0 Per detector and on-board scene 25km across-track x 23km along-track S2MSI1A Per detector and along-track on-board scene size S2MSI1B 25km across-track x 23km along-track Along-track band co-registration is performed w.r.t. one reference band of the L0 scene S2MSI1C 100km x 100km UTM tile Tiles are identified on a fixed world reference system based on UTM zones Table 4-3 Sentinel-2 Product Granularity Figure 4-10 illustrates this concept in the particular case of the Level-1C products where a granule corresponds to a portion of the global world surface in the UTM projection, called a tile. For such products, the product tiles will be preset and consistently identified on a fixed global world reference system based on UTM zones. This feature shall facilitate the data management for multi-temporal applications while fostering the multi-temporal registration requirements of the measurements at pixel level (cf. section 4.4.4.1 about the Level-1C Quality Baseline) ESA UNCLASSIFIED – For Official Use © ESA The copyright of this document is the property of ESA.
