SNAP User Forum – Presentations available

10 September 2019 @ 11:30-16:05; Magellan B Room

The Sentinel Applications Platform (SNAP) is a data analysis framework ideal for the exploitation of Earth Observation data. SNAP is an open-source solution with a number of toolboxes and plugins that allow its users to analyse Radar (e.g. Sentinel 1 SAR) and Optical data (e.g. Sentinel 2 and 3).
Join the event to get to know about SNAP, its future and example usage by Industry and Academia. Share your views of SNAP and tell ESA and the SNAP Developer team how SNAP can be improved.

11:30 – 13:30 – SNAP User Forum – Presentations and Discussion
Moderator: Cristiano Lopes, ESA

SNAP User day 10 September 2019

ESA SNAP is the free and open-source multi-mission toolbox for post-processing and analysing ESA and 3rd party EO satellite image data.

SNAP User Forum is an event where users will be able to exchange their experience with the use of SNAP. It will be organised around oral and hands-on sessions where newcomers can get to know all about SNAP and where existing users can potentially learn news tricks.

A Tentative Agenda would be

– Welcome Session

  • ESA – Intro to the day
  • SNAP Team – Intro do SNAP (user perspective), who is doing SNAP, how can you help, what’s new (last year or so)
  • Terradue – Keynote: Use of SNAP for an operational use.

– Others Talks

  • Examples of user usage of SNAP in the desktop
  • Examples of user usage of SNAP in a data centre own use
  • Examples of user usage of SNAP by service providers

– Q&A Session

  • Open Discussion – what’s great, what needs improvement, what’s missing

– Workshops (parallel threads)

  • Install Party / Intro to SNAP (usb stick giveaway with portable snap and data)
  • Processing with SNAP for SAR
  • Processing with SNAP for Optical
  • SNAPpy (pySNAP)

Presentations should follow these guidelines
> In what context are you using SNAP, which parts and to do what?
> What other software do you use along with SNAP? Do they have to interact with each other?
> What works and what doesn’t?
> What performances do you get (time, quality)?
> What extra SNAP feature would help your work?
> Did SNAP help you achieve everything that you expect it to?

The main outcome of the event for ESA is to gain a deeper understanding of user needs and user experiences with SNAP. For the user the outcome is to get to know SNAP and to know that SNAP is being actively developed and that they can count on a community to support them.

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/
With best regards,

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.
