ESA Summer of Code in Space 2016 S1TBX Ideas

The ESA SNAP S1TBX team is applying to become a mentoring organization in the ESA Summer of Code in Space programme. We hope to find the brightest and most creative student open source developers to help us add new and exciting possibilities to SNAP and the Sentinel-1 Toolbox.


ESA Summer of Code in Space 2016 (SOCIS 2016) is a program run by the European Space Agency. It aims at offering student developers stipends (4000 Euros) to write code for various space-related open source software projects. Through SOCIS, accepted student applicants are paired with a mentor from the participating projects, thus gaining exposure to real-world software development scenarios. In turn, the participating projects are able to more easily identify and bring in new developers.



We are looking for intermediate level Java developers from undergrads to PhD’s with some experience with geospatial software.

Proposed projects must be achievable within the limited project timeline.

Students have until 15 May 2016 to apply.

Project Ideas

Below are some suggested ideas or submit your own idea. Please complete a two page proposal describing what you intend to do, how you will achieve it and why you are best suited for the job.

1) Develop basic tools for statistical analysis, machine learning, segmentation, feature extraction and classification or integrate from existing open source libraries such as RapidMiner, Weka, Mahout, DL4J, etc.
required: java
priority: high

2) Enhance the GIS capabilities of SNAP with integration from other Java GIS software such as Geotools, Geolatte, JTS, etc. Improved vector handling, additional vector format import/export with OGR, etc.
required: java, GIS
priority: moderate

3) Support for a targeted application area such as ice classification, environmental monitoring, monitoring of surface movement, ocean applications, forestry, agriculture, security, ship classification etc. Develop enhancements for the application area and create tutorials to showcase the application.
required: java, knowledge of SAR application area
priority: high

4) Further integrate NASA WorldWind into SNAP adding support for new capabilities. Implement some example applications combining WorldWind and SNAP EO features.
required: java, opengl, worldwind
priority: high

5) Include new InSAR functionality for SBAS, PSI or atmospheric correction through development of new tools or improved integration with existing open source tools such as GIAnT, STAMPS or TRAIN.

required: java, knowledge of InSAR
priority: moderate


Please contact us here.
Applications must be submitted on the SOCIS website.

If you are not a student at an ESA member state but would still like to contribute to the above ideas, please contact us and we could still provide mentorship.

SNAP 3.0 is now available

The SNAP development team is pleased to announce the final SNAP 3.0 release which is now waiting to be downloaded.
Beside bug fixes and improvements, several new features are waiting for you. For example

  • a new Resampling Operator has been introduced.
  • GPF operators can now handle multi-size products
  • quicklooks are now supported in the Product Explorer and the Product Library

For more information about changes made for this release please have a look at the release notes of the different projects: SNAP, S1TBX, S2TBX, S3TBX, SMOS Box.

Enjoy the new release

SNAP 2.0.2 is now available

The SNAP Development team is pleased to announce the final SNAP 2.0.2 release which is now waiting to be downloaded.
Beside several bug fixes, we decided to redesign the installers. They now bundle the toolboxes instead of downloading them in order to avoid network problems during installation. Existing installations can also be updated via the plugin manager, as usual.

More SNAP Video Tutorials

The series of SNAP tutorials has been augmented with videos covering the following subjects:

  • Open and explore a Sentinel-2 product;
  • Using band arithmetic;
  • Performing a re-projection of a product;
  • Extracting a subset of a product;
  • Computing a NDVI and interpreting the results;
  • How to export/save the product and/or the current view.

The tutorials can be found in the section DOCUMENTATION -> TUTORIALS . The section will be updated with more videos that will help you through the process of executing different operations in SNAP. Enjoy!

New Video Tutorials

Today we published some new video tutorials, showing the basic functionalities of SNAP. For example they show the usage of the Mask Manager, the Colour Manipulation Tool and how to use pins and the spectrum tool. The videos are available in the tutorial section. More videos are planned.

SNAP Toolbox Components for Download

It has been reported in some rare cases that the installation of SNAP components from within the installer fails due to download errors. This happens for several reasons, problems with internet proxy, restrictive firewall settings or general connection problems. Therefore we now provide all toolbox components in one archive for download. Note this is only optional. In general you can rely on the download within the installer. However, providing these components also allows users to put everything on a DVD or USB-Stick and install SNAP and the Sentinel Toolboxes on a system without internet connection. The archive file is provided on the download page.

SNAP 2.0 Out Now!

The SNAP Development team is pleased to announce the final SNAP 2.0 release which is now waiting to be downloaded. Enjoy!

Dear beta testers, please uninstall your SNAP beta versions and make sure to let the installer delete previous SNAP data directories. And again thanks so much for your patience, feedback, and support!

SNAP 2.0 beta 8

The 8th beta release of SNAP is ready for download. Again this updates comes with many fixes and improvements, we have considered several comments and issues which were sent to us via the forum. This release contains the SMOS Toolbox for the first time. We also performed a major Java API revision and we were forced to change the SNAP configuration. If you encounter any problems with this new version, please consider removing your SNAP user data which is found in the “.snap” directory of your home folder.

To get this new version, it is required to uninstall the previous version of SNAP and request a participation to the beta test programme
from the download page: If you have already applied for the beta test programme you can reuse the download links from the mail which was sent to you.

Sentinel Toolbox Hackathon on 15-16 Oct 2015 in ESRIN
