GRASS Community Sprint Bonn 2016

During the FOSS4G 2016 , 21-28 August 2016, Bonn, Germany, the GRASS GIS project will join the code sprint

Important dates:

• CodeSprint I: Sun 21.08.2016 12:00 - Tue 23.08.2016 (open end) (see also here)
• FOSS4G 2016 Schedule
• CodeSprint II: Sat 27.08.2016 - Sun 28.08.2016 12:00 p.m. (see also here)

Purpose

Get together of GRASS GIS project members to take decisions and tackle small and larger problems.

For this meeting, we welcome people committed to improving the GRASS GIS project. This includes developers, documenters, bug reporters, translators, and users!

Sponsors

If you are interested to sponsor the GRASS Community Sprint, please read about
    sponsoring the GRASS project at http://grass.osgeo.org/donations/
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 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 Bonn. 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.

Testing

Please test in GRASS 7.2.svn!

• d.legend.vect

Improvements

• improve r.modis addons
• integrate Google Summer of Code projects (where adequate)
• continue working on OBIA toolchain:
  • Testing of mean shift in i.segment
  • Finalization of r.object.geometry and its integration into i.segment.uspo

Better integration of git into development

• since github/gitlab/bitbucket etc are a valuable and recognized source of new source code, we should be able to receive such contributions easily
  • OSGeo currently deploys a self-hosted "gitlab" repo: https://lists.osgeo.org/pipermail/sac/2016-August/007345.html
