3rd EO Open Science Conference, 25–28 September 2017

Dear users,

The European Space Agency (ESA) is organizing the 3d consultation meeting of EO Open Science in ESRIN (Frascati, Italy) on 25–28 September 2017 to explore new challenges and opportunities for EO research created by the rapid advances in Information and Communications Technologies (ICT). This includes open tools and software, data-intensive science, virtual research environment, citizen science and crowdsourcing, advanced visualization, e-learning and education of the new generation of EO and Data scientists. The conference is presenting activities in EO Open Science and Innovation and develop a Roadmap for future ESA exploitation activities under the EO Science for society programme. Please find more details on the official website http://eoopenscience.esa.int/. You can follow the live stream here.

7th Advanced Training Course on Land Remote Sensing, 4-9 September 2017

As part of the Scientific Exploitation of Operational Missions (SEOM) programme element, the European Space Agency (ESA) organised an Advanced Land Training Course devoted to train the next generation of Earth Observation (EO) scientists to exploit data from ESA and operational EO missions (e.g. the Sentinels) for science and applications development.

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.

Please find more details on the official website http://eoscience.esa.int/landtraining2017/.

New release of Sen2Three 1.1.0 is available

Sen2Three is releasing the new version 1.1.0 available to be downloaded from here.

Changes of release 1.1: Compatibility with PSD version 14.2 and Sentinel 2B products

  • Sen2Three supports now the “safe compact” format which was introduced with PSD version 14.2 in parallel to the safe standard format as it was used up to PSD version 13.1. Sen2Three will detect the format automatically when reading a product. No configuration changes are necessary. The Level 3 output will always be generated in the PSD version 14.2 compatible safe compact format.
  • If Sen2Three is detecting a version 13.1 formatted Level 2a input product, it will convert it first into a version 14.2 compatible safe compact Level 3 product and processes it afterwards. This allows a mixed input of Version 13.1 and 14.2 Level 2a products in the same directory at the same time.
  • Sen2Three now also supports the processing of Sentinel 2B Level 2a input products and is compatible to Sen2Cor Version 2.4.0.

For any questions about the installation or usage of Sen2Three, please follow the STEP forum areas dedicated to Sen2Three:

New release of Sen2Cor 2.4.0 is available

Dear Users,

we are pleased to provide Sen2Cor Release 2.4.0 under:
http://step.esa.int/main/third-party-plugins-2/sen2cor/

Due to the numerous installation problems which have been reported in the past, which are mostly related to evolutionary shifts between the different Sen2Cor releases and its Anaconda runtime environment and/or its associated tools, we have now developed a series of stand-alone installers for the three operating systems Linux, Windows and macOS. All three versions require a 64-bit platform.

After download and installation, these packages will work fully autonomously, isolated, and do not need any further installation of Anaconda, GDAL, OpenJPEG or any other python packages.

Although this is the first official release of the standalone installers, we strongly recommend testing these simplified installation first, as it will prominently reduce the installation
overhead in contrast to a full Anaconda installation, especially as changes in the interfaces of anaconda packages might occur after the release of a Sen2Cor version.

For a short introduction of how to install the stand-alone versions of Sen2Cor, read the following thread in the ESA STEP Forum: http://forum.step.esa.int/t/sen2cor-2-4-0-stand-alone-installers-how-to-install/6908

If you observe any issues during installation or usage of the standalone installers, please reply to this thread, with an explicit information on which operating system the issue occurred. Please, do not open a new thread, as it will be difficult for us to track the problems, if multiple threads with the same topics exist.

For a collection on recent issues with the Sen2Cor2.4.0 Anaconda Version, please use this thread: http://forum.step.esa.int/t/sen2cor-2-4-0-anaconda-based-version-recent-issues/6909

with an explicit information on which operating system the issue occurred. Please, do not open a new thread, as it will be difficult for us to track the problems, if multiple threads with the same topics exist.

For any further details and an overview on the evolutionary upgrades and corrective maintenance fixes applied to Sen2Cor 2.4.0, please read section 3.1.1 of the release notes which are provided under: http://step.esa.int/main/third-party-plugins-2/sen2cor/

With best regards,

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
