New release of Sen2Cor 2.8 is available

Dear Users,
we are pleased to provide Sen2Cor Release 2.8 under: http://step.esa.int/main/third-party-plugins-2/sen2cor/sen2cor_v2.8/
Stand-alone installers for the three operating systems Linux, Windows and macOS are now available. All three versions require a 64-bit platform.
Regarding the algorithm, the main improvements of the Sen2Cor 2.8 processor compared to previous version 2.5.5 are:

  • Support of the L1C generated with the current (14.5) and previous (14.2) Products Specification Document, as input.
  • Improvement of the spatial homogeneity of surface reflectance between adjacent tiles.
  • Improvement of the terrain correction algorithm in mountainous areas, in order to avoid artefacts for pixels under semi-transparent clouds.
  • Improvement of the terrain correction algorithm, in order to avoid adjacent tile discontinuities in terrain correction for seemingly flat areas with gentle slopes.
  • Improvement of the Scene Classification of snow/ice, enabling the detection of snow above frozen lakes and icebergs in Arctic and Antarctic Sea.
  • Improvement of the RAM consumption, which is now less than 4 GB.
  • Optimization of the JPEG2000 files reading time with the support of OpenJPEG 2.3

The Sen2Cor SNAP adapter works with Sen2Cor 2.8 (PSD 14.5 and 14.2) and Sen2Cor 2.5.5 (PSD older than 14.2). The adapter will be updated soon and a new plugin update version will be published.
For any further details, including installation step, and an overview on the evolutionary upgrades applied to Sen2Cor 2.8, please read the release notes which are provided under: http://step.esa.int/main/third-party-plugins-2/sen2cor/sen2cor_v2.8/

STEP Forum live again, but some DNS changes may take awhile

Dear STEP Users,

The Forum is live again. It can be accessed at the following address: https://forum.step.esa.int.

Please note that some DNS changes operated today may take awhile to be applied for everyone. The read-only copy of the forum will be accessible in the following days, until the changes are applied. If the forum is NOT read-only, it means it is pointing to the latest version of the forum, and the DNS changes were applied on your computer.
We are still working on some areas of the forum, so you may notice small issues. You can help us by describing the encountered issue in the meta category of the forum (https://forum.step.esa.int/c/meta).

We are continuously working on improving our platform, to offer the best experience.

The STEP Team.

STEP Forum read-only on 22nd of May, 2017, between 5 AM UTC and 15 PM UTC

Dear STEP Users,

Please be informed that the STEP forum will be read-only tomorrow, 22nd of May, 2017, between 5 AM UTC and 15 PM UTC. This means the forum will be able to display posts, but not to save new posts or other actions. This operation is part of periodic administration operations, and has the scope of assuring and improving the accessibility and responsiveness of the STEP platform (including the public website and the forum).

We are working as fast as possible to reopen the forum. A new post will inform when the operation will complete.

We are sorry for any possible inconvenience and we are continuously working to improve our services.
Thank you for your understanding.

The STEP Team.

LE: The forum is live again, but some DNS changes will not take effect right away and for everybody in the same time. Please note that, if the forum that you see is read-only, you are seeing a backup of the forum. It may help to clear the browser cache. Otherwise, try again in a few hours.

New release of Sen2Cor 2.5.5 is available

Dear Users,

we are pleased to provide Sen2Cor Release 2.5.5 under: http://step.esa.int/main/third-party-plugins-2/sen2cor/
Stand-alone installers for the three operating systems Linux, Windows and macOS are now available. All three versions require a 64-bit platform.

Note, that a product format change has been applied to the data products:

  • The naming logic of the files embedded in the L2A product package has been harmonised with that of the L1C product
  • The Metadata files (Product, Datastrip, and Tile levels) have been harmonised in structure and contents with that of the L1C

Regarding the algorithm, the main improvements of the Sen2Cor 2.5.5 processor compared to previous version 2.4.0 are:

  • Improvement of cloud screening and scene classification
  • Visibility iteration extended from 80 to 120 km
  • Exclusion of cloud shadow pixels for Water Vapour retrieval
  • Improved aerosol optical thickness retrieval

The Sen2Cor SNAP adapter (plugin version 6.0.1) is working with Sen2Cor 2.4.0. The adapter will be updated soon and a new plugin update version will be published.

For any further details, including installation step, and an overview on the evolutionary upgrades applied to Sen2Cor 2.5.5, please read the release notes which are provided under: http://step.esa.int/main/third-party-plugins-2/sen2cor/

OGC Announces Earth Observation Exploitation Platform Hackathon 2018

Dear users,

The Open Geospatial Consortium (OGC®), together with the European Space Agency (ESA), and Natural Resources Canada (NRCan) is organizing the Earth Observation (EO) Cloud Processing Hackathon. This Hackathon provides a business opportunity for stakeholders to experiment with the latest results from Testbed-13 in the context of ESA’s Earth Observation (EO) Exploitation Platforms.

The Hackathon will run from March to May 2018, with a Clarification Webinar for prospective participants on February 19. A Kickoff Workshop at OGC’s Technical and Planning Committee Meeting in Orléans, France (attendable remotely) will mark the beginning of the Hackathon.

Organizers will provide the Sentinel Application Platform (SNAP) Software Toolbox together with a pre-defined workflow packaged in a Docker container. Thus, Hackathon participants can use the Docker container “as is” and do not need to modify the container or the application. The SNAP workflow in that Docker container requires two types of data: Digital Elevation Model (DEM) data and Sentinel-1 data. Both will be made available to the participants as cloud resources.

During the Demonstration Meeting, participants will have the opportunity to visit the ESA Operations Centre in Darmstadt (Germany), including the Main Control Room.

The master schedule of the event, together with other details and clarifications, can be found on the official page of the event: http://www.opengeospatial.org/projects/initiatives/eocloudhack.

A total of 78 post graduate-level, PhD students, post doctoral research scientists and users from Europe, Canada and from other continents attended the 6-day course, which was held at Szent István University (SZIU), Hungary, from 4 to 9 September 2017.

Objectives
The Advanced Land Training Course aimed at:
Training the next generation of European and Canadian Principal Investigators (PIs)
Explaining theoretical principles, processing algorithms, data products and their use in applications
Introducing tools and methods for the exploitation of EO sateliite data, in particular the Sentinels
Stimulating and supporting the exploitation of ESA EO and Third Party Mission data for land remote sensing science and applications.
