STEP Forum not available today, 7th of June, 2017 from 8 PM UTC to 10 PM UTC

Dear STEP users,

For scheduled maintenance tasks, the STEP forum (http://forum.step.esa.int) will not be accessible today, 7th of June, 2017, from 8:00 PM UTC to 10:00 PM UTC. We are sorry for any inconvenience and we hope that the forum site will be available again, shorter then we planned. Thank you for your understanding.

The STEP team.

New releases of Sen2Cor 2.3.1 and Sen2Three 1.0.1 are available

Sen2Cor is releasing the new version 2.3.1 available to be downloaded from here. This release is a corrective maintenance upgrade based on release 2.3.0 and includes the following fixes:

  • SRTM DEM artefacts improvement in coastal areas;
  • Fixed errors in SRTM contour lines for terrain with gentle slopes;
  • Metadata update of quality indicators for cloud coverage percentage;
  • Fixed multiple occurrences of B08 band in the metadata at 10m resolution;
  • Improved deviation for the case when a tile contains a huge amount of water and only few parts of land;
  • Correction for abnormal termination in case a SRTM DEM is not available for a selected tile;
  • Cirrus correction has been deactivated as issues with cirrus correction have been observed.

More details about the features and fixes and about the older versions can be found in the release note.

Sen2Three is releasing the new version 1.0.1 available to be downloaded from here. This release fixes an incompatibility with Sen2Cor release 2.3.0. Due to an upgrade of the IO routines of the Sen2Three processor (release 2.3.0 and above), which allowed to inherit the positional information from the Level 1C data, Sen2Three was
no longer able to process the according Level-2A data, due to read errors of the modified Level-2A inputs. This has been fixed now. Additionally, Sen2Three is now able to inherit the positional information as received from the Level-2A inputs. More details about the features and fixes and about the older versions can be found in the release note.

For any questions about the installation or usage of Sen2Cor and Sen2Three, please follow the STEP forum areas dedicated to Sen2Cor and Sen2Three:
http://forum.step.esa.int/c/s2tbx/sen2cor

Enjoy!

New survey: SNAP usage in operational context

The SNAP development team is valuing user’s opinions. That’s way we invite the community to take a survey, available here, with the intention to identify any technological gaps when using SNAP in operational contexts. Please note, the more specific and detailed your feedback is, the better we can imagine, plan, specify what need to be developed in the future!

New release of Sen2Cor is available (version 2.3.0)

Sen2Cor is releasing the new version 2.3.0 available to be downloaded from here. The new features of this release include:

  • Support of PSD both current PSD 13.1 and future PSD 14.2;
  • Improvement of blue path radiance calculation (reducing the tiling effect on large areas);
  • New Quality Indicator for cloud coverage percentage;
  • Improved up- and downsampling routines;
  • Several bugs fixed (e.g. DEM artifacts).

More details about the features and fixes and about the older versions can be found in the release note.
The installation procedure available in the user manual should be followed.
For any questions about the installation or usage of Sen2Cor, please follow the STEP forum area dedicated to Sen2Cor: http://forum.step.esa.int/c/s2tbx/sen2cor.

Enjoy!

Sentinel-3 OLCI L1b data publicly available

Today ESA and EUMETSAT announced availability of Sentinel-3 OLCI L1b data from now on. All data acquired onwards will arrive in near-real time at the Sentinel Data Hub (ESA) and the Earth Observation Portal (EUMETSAT). Data collected during Commissioning Phase will be reprocessed and will be made available later.

Please be aware that you currently have to use a special login to the Sentinel Data Hub. The usual login doesn’t work. The credentials are shown on the login screen when you follow the link above.

A more exhaustive news article can be found on this ESA Sentinel-3 page.

We are very happy that the OLCI data is now available and we are keen to exploit its capacity. Probably you are too.

Forthcoming Sentinel-2 L1C product evolution in Autumn 2016

By early September 2016, Sentinel-2 Level-1C products will start being distributed on the Sentinels Data Hubs in single-tile packages following the current product format and naming convention (PSD 13.1). This new packaging does not impose changes on downstream software applications compatible with the current PSD 13.1 product format.

Furthermore, by the end of October 2016, a new product format will be introduced.

This new format features the following main evolutions:

  • The product naming (including the naming of folders and files inside the product structure) has been compacted to overcome the 256 characters limitation on pathnames imposed by the Windows platforms.
  • The products distributed on the Sentinels Data Hub will embed one single tile of the tiling grid (as opposed to a set of tiles).
  • A full resolution True-Colour Image (TCI) will be included in every product as a separate RGB composite image (in JPEG2000 format) and will be placed inside the Tile folder together with the original spectral band images.

This updated product format is described in detail in the Sentinel-2 Products Specification Document (PSD) (version 14.0). Change bars on the document highlight every single change made on the document with respect to the previous version (13.1).

Users are reminded that the PSD defines the generic format of Sentinel-2 products that includes several packaging/formatting options. In that respect, it is highlighted that the specific product format that will correspond to the Level-1C product published on the Data Hub will combine the features of both the “Compact Naming Convention” and the “Complete Single Tile” options described in the PSD.

The corresponding XSD schemas and test data in PSD 14.0 will be made available by mid September.

More details about the actual product format and naming convention and other Sentinel-2 related information, please see the dedicated website https://sentinel.esa.int.
