Sen2Cor v2.11 installation packages are provided as standalone installers. For a short introduction of how to install the standalone version of Sen2Cor, read the installation steps described in Sen2Cor Quick Guide Sen2Cor_Quick_Guide_V_1_2_2.pdf
The main new features in the Sen2Cor v2.11 release with regard to the Sen2cor v2.10 include:
- Support of the input L1C products generated with the current (14.9) and previous (14.6, 14.5 and 14.2) Products Specification Document
- Identification of defective pixels from missing instrument source packets in L2A Scene Classification layer
- The use of Copernicus DEM@30m horizontal resolution
- Several Quality Improvements
It is important to know, that the default configuration of the L2A algorithm provided with Sen2Cor version 2.11 is the same configuration as for the L2A “Core” Products processing in Sentinel-2 Ground Segment with L2A processing baseline 04.00. Therefore, no further tuning should be required on user side to get L2A Products similar to L2A Core Products.
In order to generate products compatible with the L2A Core Products it is necessary to set the usage of a Digital Elevation Model to improve Scene Classification and have the activation of ESA-CCI data-package to be downloaded here and installed. The usage of ESA CCI data package for Sen2Cor v2.10 is detailed in the dedicated Software User Manual: S2-OMPC-L2A-SUM-V2.11.0.pdf.
In addition, users are informed now that Sen2Cor 2.11 is currently prepared to make use of the Copernicus DEM@90m and 30m horizontal resolution. The usage of the Copernicus DEM is detailed in the dedicated Software User Manual (section 2.2.8): S2-OMPC-L2A-SUM-V2.11.0.pdf.
Using the Copernicus DEM@90m, the only differences between L2A “Toolbox” and L2A “Core” Products are reported in the following table:
| Category of Difference | Difference | L2A Toolbox | L2A Core Products |
| Product Format | HTML Folder | No | Yes |
| Manifest | Same Set of Items but arranged in different order | ||
| Product Quality Metadata | Copied from L1C | Generated by L2A On-line Quality Check (OLQC) | |
| JPEG2000 encoding library | OpenJPEG | Kakadu | |
| Processing baseline | 99.99 | Official, e.g. 05.09 | |
The evolution of the processing baseline used to process Sentinel-2 L2A Core Products in Ground Segment are reported in the L2A Data Quality Report.
