GRASS GIS Community Sprint Bonn 2018
The GRASS GIS community will join the general OSGeo Code Sprint at BaseCamp in Bonn, following the annual FOSSGIS conference (German Speaking OSGeo Local Chapter conference in Bonn, Germany)
OSGeo Code Sprint: March 18 - 25, 2018 at BaseCamp, Bonn, Germany.
Please check more info on the Bonn Code Sprint 2018 here.
We also welcome direct financial contributions 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 GRASS GIS 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. This Bonn event is especially interesting since important OSGeo projects come together!
Agenda - What we plan to do
New GRASS GIS startup style
- To simplify GRASS GIS startup,
- first the full GUI should be shown and immediately the location dialog popped up _inside_ GRASS GIS
- default SRS: long-lat 4326
- Rationale: don't continue to be different from the rest of the world when not needed
- New solution needs to cover following scenarios:
- GISDBASE does not exist;
- GISDBASE exists, but there is no location with EPSG:4326;
- Selected location/mapset must be propagated down to background CLI process too.
- New solution needs to cover following scenarios:
Move to Git
- Choose among different options: OSGeo Git, Github, GitLab
- Participants are invited to study Git in advance :-)
- Consider moving only GRASS 8 (or 7.7) without history and push history into a separate repository. Rationale – repository checkout will have to contain all branches thus blowing-up checkout size. There is an option to use several git repos "chained" together to have access to full history without having it to live in a single repository. Here's an example: https://archive.org/details/git-history-of-linux https://stackoverflow.com/questions/161928/what-are-git-info-grafts-for
Choose among different options: Wordpress ,Sphinx, ... ? A new Wordpress installation is requested in SAC (ticket). √
- https://staging.grass.osgeo.org/ (login with OSGeo-ID)
Python interface for external usage
- complete the new "grass-session" pip package (https://github.com/zarch/grass-session)
- change packaging to for better support of site-package
Integration with QGIS Processing
After some intensive discussions the decision of the QGIS devs is to continue with the "Processing" support (see summary email by P Cavallini)
Action item: update the GRASS GIS processing provider. A boilerplate could be the new SAGA processing provider.
Port wxGUI to wxPython 4
- Finish porting wxGUI code to the new wxPython 4
- It also includes porting code to Python 3
Finish the full Python 3 support
- Includes also wxGUI support for wxPython 4

- Bring your own computer
- Bring your power connector adapter if needed (photo: Germany). See also http://www.power-plugs-sockets.com/
- Install subversion and the compiler tools, and come with a working GRASS development environment if possible.
We have to remember to take at least one group photo! :-)
- 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?
