The publication will start on Tuesday, 05 June 2018.
The campaign for republishing the Sentinel-2A L1C products from their historical format to the ‘Complete Single Tile' format continues!
Following the successful completion of the publication of the first batch of products concerning December 2016, a second batch is about to be published on the Open Access Data Hub and Copernicus Services Data Hub.
The second batch of converted products contains data acquired in November 2016 comprising of the Data Take sensing range starting from 01 Nov 2016 at 00:27 UTC to 30 Nov 2016 at 23:28 UTC and contained 106428 products in total.
The list reporting the correspondence between the old formatted products (i.e. filename and UUID) and the converted products is provided here.
The old format data will be removed incrementally after the publication of the new product. Users who routinely automate the download of the new products should be aware that a significant volume of historical data will be published, and that these data may be re-downloaded automatically based on their ingestion date unless precaution is taken in the download scripts and workflows.
The overall affected dataset that will eventually be published covering the sensing period from 04 July 2015 to 06 December 2016 (Sentinel-2A only). Approximately 340 thousand existing products will be repackaged, creating over 1.3 million new products.
The republishing will cover the reformatting of the historical data-set of Sentinel-2A Level 1C products which do not feature either the Compact naming or the Complete Single Tile packaging characteristics into their ‘Complete Single Tile' equivalent structure with the Compact naming representation.
The main features of the converted products as compared to their former counterparts are summarized below:
- The radiometric and geometric quality of the products will remain unchanged. Coherently with this, the Processing Baseline identifier (PB) tagging every product will also remain unaltered (i.e. expected between PB 02.01 and 02.04), and will keep tracing the quality of the data outlined in the data quality report, in relation to the processing baseline.
- The product formatting will comply with the Sentinel-2 Product Specifications Document (PSD) issue 14.2(*). In line with this format, the repackaging will take care of adding the TCI image inside the new products structure.
(*) It is highlighted that PSD 14.2 used for the repackaging will provide continuity with the format introduced on 06 December 2016 and used up until the end October 2017. Consequently, the generated products will not embed the subsequent evolution of the product format introduced on 23 October 2017, starting with PB 02.06.
