GRASS Community Sprint Prague 2013

The GRASS GIS team will organize the 4th GRASS Developer and Power User Meeting, aka 'GRASS GIS Community Sprint' from July 12 to July 18, 2013. The sprint is following the Geoinformatics conference, 11-12 July 2013, Czech Technical University in Prague, Czech Republic.

Important dates:

• 11 (Thursday) - 12 (Friday) July 2013: Geoinformatics conference

• 12 (Friday) - 18 (Thursday) July 2013: GRASS GIS Community Sprint @ FCE CTU

Purpose

This fourth edition of the GRASS GIS Community Sprint 2013 is a great occasion for folks to support the development by actively contributing to the source code, manuals or likewise. The community sprint is a get-together for GRASS project members and supporters and related OSGeo projects to make decisions and tackle larger problems. For this meeting, we welcome people committed to improving the GRASS GIS project and the interfaces to QGIS, GDAL, PostGIS, R statistics, Sextante, gvSIG, OGC Services (esp. WPS) and more. This includes developers, documenters, bug reporters, translators and others.

For this meeting, we welcome people committed to improving the GRASS GIS and related projects. This includes developers, document writers, wish and bug reporters, translators etc.

Sponsors

We welcome financial contributions to support the meeting and we are looking for sponsors to cover costs such as meals or to help reducing travelling and accommodation expenses for GRASS developers with far arrival If you are interested to sponsor the GRASS Community Sprint, please read about

sponsoring the GRASS project at http://grass.osgeo.org/donations

Note that it is also possible to buy a round of beer for the developers with a quick click using the PayPal "Buy [pizza/beer/...] Now" button

For any questions, please contact Markus Neteler <neteler at osgeo.org>. Any surplus at the end of the event will be turned over to the GRASS GIS project.

This fourth GRASS Community Sprint is a great occasion for you to support the development of GRASS. With your contribution you'll enable more developers to meet. The community sprint is an important opportunity for the GRASS developers to discuss and collaboratively resolve bugs, plan the direction for the project and work on new features. Please see below for the more detailed agenda. The developers and contributors are donating their valuable time, so it would be great if in-kind funding can be made available from within the community to cover out-of-pocket expenses. All of the work that takes place at the community sprint will be directly contributed back into the GRASS project to the benefit of everyone who uses it.

Hangout/Videobridge

There is the option to use Google+ Hangout, it's limited to 10 people and may require everyone to have G+ social media accounts to participate. (?)

Similarly multi-video conference calls can be done with Skype if the conference call initiator is a paid-up commercial Skype customer.

The FOSS Jitsi VoIP, IM, and video conferencing software produces a trivial to set up VideoBridge server software to the same.

Further discussion on the pros and cons of these can be found on the Talk side of this wiki page.

Collaborative document scratching

(Power) users from all over the world are kindly invited to assist with testing of new and existing functionality. To collect results and notes, we set up an interactive, collaborative editing tool (an Etherpad instance) which works in real-time:

Individual Preparation

• Bring your own computer
• Bring power connector adapter if needed (Czech Republic: 230V, 50Hz, Type C Europlugs are common and also Type E)
• Install subversion and the compiler tools, and come with a working GRASS development environment if possible.
