Hackathon supporting the Sentinel Application Platform (SNAP)
In the framework of the EO Open Science 2.0 conference, ESA is organising the first Hackathon event bringing together volunteered programmers with the developers of the Sentinel Application Platform (SNAP) to intensify understanding of SNAP and to jointly develop a software using and/or extending SNAP. The SNAP Hackathon will take place on 15 Oct (9:00-19:00) and 16 Oct (9:00-14:00) in ESRIN (Frascati) just after the EO Science 2.0 conference.
Participants shall be enthusiastic developers who love solving challenging problems with a cool piece of software. Participants should have a good knowledge of the Java programming language, interest in developing tools to exploit EO data, and possibly some experience with the BEAM API before (an introduction will anyway be given to new-comers). Because of limited space we will have to select candidates based on their motivation.
Agenda for EO Science 2.0 Hackathon Event
ESRIN, 15./16.10.2015
Day 1, Part 1 (Presentation & Demos, SNAP team, 1 hour)
- SNAP team give STEP & SNAP introduction, present project status and community platform, provide an outlook
- SNAP team introduce SNAP software architecture and show applications, the most important application programming interfaces (APIs), and the documentation
Day 1, Part 2 (Question round, SNAP team and participants, 1 hour)
- Occasion for participants to ask SNAP team general "How to...?" and "Can I...?" questions
- SNAP team is happy to receive your questions before the Hackathon
Day 1, Part 3 (Hackathon, SNAP team and participants, Rest of the day)
- Participants agree upon 2 or 3 considerable-sized programming tasks
- Together, SNAP team and participants work out high-level solutions in the first step
- In the second step, do "Aquarium Programming", where participants watch SNAP developers write code on the big screen, while following them in their own development environment
Day 2, Part 4 (Hackathon ctd., SNAP team and participants, 4 hours)
- Continue and finish work of day 1
- Reap the benefits! Run and play with the newly developed tools
Day 2, Part 5 (Close Hackathon, 1 hour)
- Gather ideas for future ESA hackathons and/or prize-giving coding challenges
- Gather feedback regarding the current state of the SNAP application, its APIs and libraries
- Discuss other possible applications and use-case scenarios of SNAP and SNAP APIs
- Discuss further evolution of SNAP, the Sentinel Toolboxes, and its potential adaptation to other missions
Set up a development environment before the Hackathon:
- Install a Java JDK 8.x (use Oracle JDK, not OpenJDK!)
- Install Apache Maven
- Install git
- Install an IDE (IntelliJ IDEA recommended)
- Follow the instructions given at https://github.com/senbox-org/snap-engine/blob/master/README.md
