Code Sprint

Venue: Boston, Massachusetts, United States

This year, once again, we are following the old tradition of hosting a code sprint right after FOSS4G 2017. The code sprint will be held Saturday August 19th, 2017 at District Hall (

Participation in the code sprint is free of charge and all folks currently involved or interested in getting involved in OSGeo community projects are welcome.

This is open to all who wish to participate in one or more projects. There’s always plenty to do – it’s not all about programming. Translation, documentation, feedback, discussions, and testing are also very important for projects! Registration with the conference is not a prerequisite for participation in code sprint.

If you plan to attend, please signup in the table below. If you are unable to sign up, you are still welcome to attend the Code Sprint and we'll add your name when you get to the Sprint.


One thing we’d like to ask you: with over 200 participants anticipated, the WLAN capacity will naturally be exhausted at some point. Please be sure to avoid huge on-site downloads of data, as this could impact the work of others. Thank you!

The Codesprint Organizing Team is looking forward to your coming!

In summary:


  • Saturday August 19th 9AM - 5PM

Registered Attendees

The Code Sprint does not cost any money. For us it makes planning easier if we know who is coming. So please leave your Name.

Getting the most of a code sprint takes a lot of prep. Please use this area to decide on a topic, sort out a plan of attack.

Please keep in mind that the FOSS4G conference is an outreach event. Some of the "new" volunteers are learning about open source for the first time, consider listing some activities (and perhaps having a mentor on hand to facilitate).

Website Training

OSGeo website training is available throughout the day, please mark your name down to attend. We ask that a member of each OSGeo committee, local chapter, geoforall lab make plans to attend. Service providers and sponsors are also welcome.

We will be reviewing both the website publication workflow and the about.yaml structured content used by the project working group.

Attending: Jody Garnett, Jeffrey Johnson, Gérald Fenoy


Introduce members to the new website, editing workflow, and add to the members map.

Stop by to create your own personal "osgeo branding" using InkScape.

Answer any questions projects have on about.yaml use.

Add to the collection of presentations, videos and tutorial links.
