* idea from Venkatesh: provide a power-packed FOSS4G/OSGEO CD to the participants and maybe keep a few CD-RW equipped machines so that people could burn their own CD at the Conference venue. This is particularly use to participants from countries where internet bandwidth is narrow. The FOSS4G CD might be a good (release) candidate for the FOSS4G/OSGEO CD if it could be further tested, polished and improved upon.

Introduction: FOSS4G 2006

Geoinformatics 2006 is to be held in Lausanne, Switzerland, over September 12-15th 2006 and we offer several workshops and presentations. This page will hold the plans and proposed programme for the GRASS component of Geo2006. Please compare with the official workshop time table including all offered workshops.

Workshops

For each proposal we'll have to write an abstract and submit it by 15th of april 2006 (http://www.foss4g2006.org). Any suggestion and contribution is welcome. Next FOSS4G2006 IRC meeting is in IRC (irc://irc.freenode.net/foss4g2006), see the channel topic for dates. To submit a workshop proposal one teacher needs to feel responsible as head and add the workshop.
