GSC Sentinel-2 PDGS OCD Issue 1 Revision 2 (draft) - 25.07.2010 GMES-GSEG-EOPG-TN-09-0008 page 286 of 350 6.12.3 OPERATION SCENARIOS 6.12.3.1 True Colour Images Database Build-Up/Update This operation scenario stands for the autonomous creation and update of the Sentinel-2 true colour images database to be published towards the users. The OLIB function creates a catalogue based on the available true colour images production. This catalogue encapsulates the Sentinel-2 products components breakdown (i.e. the TCI product data items) and their archive location in the PDGS. The following steps are identified for this operation scenario: 1) The OLIB function autonomously gathers and processes the new available metadata and browse images supplied by the PDGS/DAX function; 2) The new metadata is consolidated and according to the TCI database scope, the relevant TCI product data items are downloaded by use of the PDGS/DAG function (client side); 3) The OLIB function consolidates the downloaded TCI product data items and updates caches areas for streaming and download. This scenario aims for grouping all the OLIB function server side activities in preparation of the images publishing towards the users. 6.12.3.2 True Colour Images Streaming This operation scenario stands for user navigation activities on the published Sentinel-2 True Colour Images (TCIs). Triggered by the user interactions (i.e. navigation on a map) on the TCI Browser (i.e. OLIB client side), the OLIB function streams the required TCIs. The following steps are identified for this operation scenario: 1) The TCI Browser connects to the OLIB function server side for presentation of available imagery to the user; 2) The TCI Browser can optionally support the images presentation based on the local cached images from previous connected sessions; 3) The user through the TCI Browser navigates and visualises the desired map areas. Accordingly, the OLIB function server side streams the required imagery (e.g. via JPIP) to the TCI Browser; 4) The TCI Browser caches the received imagery to minimize the imagery requests to the server side and optionally support “off-line” navigation activities. 6.12.3.3 True Colour Images Download This operation scenario stands for the Sentinel-2 True Colour Images (TCIs) download by the user. Derived from the previous operation scenario, the user may request to download the full resolution TCIs (e.g. via a HMI interaction such as a polygon definition) that have been previously streamed and currently showed in the TCI Browser.

GSC Sentinel-2 PDGS OCD Issue 1 Revision 2 (draft) - 25.07.2010 GMES-GSEG-EOPG-TN-09-0008 page 287 of 350 The TCI Browser identifies the required product-data items according to the OLIB function catalogue information and then relies on the DAG function (client-side) for the subsequent product data items download activities. 6.13 Long-Term Archive (LTA) Operations 6.13.1 PRINCIPLES The LTA service function is responsible of the long-term data preservation service implementation ensuring all mission data is safely stored at least 25 years after end-ofmission. 6.13.2 OPERATION CONSTRAINTS The LTA service function operations will be performed through different distributed centres. Such operations involve a high data load plus a long time duration operations. Perform reliable archive and inventory in at least two redundant European sites for Sentinel-2 mission lifetime during at least 25 years after the end of space-segment operations; Make use of cost-effective storage solutions. To cope with the Sentinel-2 very high volume of data in an effective manner, LTA service function will make use of on-line, near-line and off-line storage mechanisms according to different products retrieval latency based on their ageing. 6.13.3 OPERATION SCENARIOS 6.13.3.1 Data Archive & Inventory This scenario accounts for the autonomous data archiving and inventory performed by the LTA service function. The following steps are identified for this operation scenario: 1) The LTA service function is fed by the AI function and work in a data-driven manner; 2) The LTA service function archives the received product components and inventories them accordingly; 3) On the other side, the AI function inventories as well all the data archived by its associated LTA service function. On the PACs (Processing & Archive Centres) with the long-term data preservation role assigned, the AI function instance locally deployed has associated a Long Term Archive service function to accomplish such role. Accordingly, the AI function autonomous supplies to its associated LTA service function, the data (products, auxiliary data, etc.) flagged for longterm preservation including all the data relevant to reproduce any MSI processing in the future.
