The new edition of Open Source GIS: A GRASS GIS Approach is now available! With this third edition, we enter the new era of GRASS 6, the first release that includes substantial new code developed by the International GRASS Development Team. The dramatic growth in open source software libraries has made GRASS 6 development more efficient, and has enhanced GRASS interoperability with a wide range of open source and proprietary geospatial tools. The book is based on GRASS 6.3.

Thoroughly updated with material related to GRASS6, the third edition includes new sections on attribute database management and SQL support, vector networks analysis, lidar data processing and new graphical user interfaces. All chapters are updated with numerous practical examples using the first release of a comprehensive, state-of-the-art geospatial data set. This new OSGeo Educational data set along with additional material can be downloaded from

Tyler Mitchell, OSGeo’s Executive Director, illustrates in a recent posting the many highlights from the first year of the Open Source Geospatial Foundation. Read more at

The GRASS-News editors and OSGeo Promotion and Visibility Committee announce the first combined GRASS-News / OSGeo-News volume. You can find the full pdf (5.3 MB) as well as PDFs of individual articles on the GRASS webpage:

A first edition of OSGeo-News will be published in 2007 with interesting articles covering various topics of OpenSource projects. Please visit in the next couple of weeks to find more detailed information how to submit articles.

Frank Warmerdam, president of announces that OSGeo has succeeded in hiring Tyler Mitchell as a full time executive director from November 2006 onwards. The full press release gives some background. There have been lengthy discussions if an Executive Director is needed and desired for a community driven foundation, but in the end it was decided that a hired “Ed” is essential as driving force – to get stuff done. Tyler will give organizational support for the quickly growing OSGeo community and act as “to-go” person and contact point. The idea is to give support to the various committees and act as shortcut between the various subcommunities as constituted by the OSGeo software, education and public geodata projects. Of course he will also play a major role in promoting the ideas and concepts of OSGeo around the globe. A detailed job description was prepared and approved by the board based on further reflections.

Welcome, Tyler!

The recent FOSS4G2006 conference at Lausanne, Switzerland was a great success. It was amazing to see how many people showed up and how many creative ideas they presented there. From Jody’s blog I took some of the next figures, but obviously the conference merge of this year had a longer story. The Lausanne conference was a come together of MUM, GRASS, EOGEO, Java and more folks with their various community conferences. Here a more complete version:

2002 150 people GRASS Users conference, Trento, Italy (Proceedings)
2003 90 people MapServer User Meeting, Minneapolis, Minnesota, USA (Proceedings?)
2004 150+ people FOSS4G: GRASS Users Conference, Bangkok, Thailand (Proceedings)
2004 200+ people MapServer User Meeting and Open Source GIS Conference, Ottawa, Canada (Proceedings)
2005 300+ people MUM3 – Open Source Geospatial Conference, Minneapolis, Minnesota, USA (Proceedings)
2006 500+ people Free and Open Source Software for Geoinformatics, Lausanne, Switzerland (Proceedings)

2007 you ask? We’ll see, will publish the call for hosting the conference soon. Some ideas are already floating around. Having 500+ people is nice, maybe we should not aim at 1000+ …
