Purpose

This second edition of the GRASS GIS community sprint 2012 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/donation.php

and, if needed, contact Markus Neteler <neteler at osgeo.org>. Any surplus at the end of the event will be turned over to the GRASS GIS project.

The first 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 in Prague. 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.

Thanks to our sponsors

We are grateful for the support which we have received to organize this GRASS Community Sprint:

Accommodation and Costs

Participants should plan for the following costs:

  • The participation is free of charge

In Prague you can have a full meal (see Czech cuisine) for still 75 - 150 CZK (3 - 6 euros), but beware of tourist restaurants, the price can easily rise. It's quite easy to find in Prague also Italian or Chinese restaurants.

FAQ

  • How was it last year?
  • Is the GRASS Community Sprint just a coding event?
    • It is mainly a coding and documentation event. It is a working session for people who are already participants in the GRASS project and/or are committed to improving the GRASS project.
    • On demand we can do some presentations of current working GRASS implementation and new upcoming features to spread the idea of Open Source GIS software
  • Is the GRASS Community Sprint for developers only?
    • No: anybody can help, with testing, checking out bugs and fixes, documentation and more.
  • Where can I get help and more information about the community sprint?
