Tag Archives: FOSS4G

Over the last two weeks, I had the pleasure to attend both the international FOSS4G conference in Bonn, Germany, as well as the regional FOSS4G-NOR in Oslo, Norway. Both events were superbly organized and provided tons of possibilities to share experiences and find new inspiration.

Talks at both conferences have been recorded and can be watched online: Bonn / Oslo

I enjoyed having the opportunity to give two very different talks. In Bonn, I presented work on pedestrian routing and navigation, which was developed within the PERRON project:

It was particularly nice that we had plenty of time for Q&A after this presentation since only two talks were scheduled for this session rather than the usual three. I’d also like to thank everyone for the great feedback – both in person and on Twitter!

In Oslo, I had the honor to give the opening keynote on OpenSource in general and the QGIS project in particular:

2 – Anita Graser – QGIS – A Community-powered GIS Project from krokskogstrollet on Vimeo.

Both conferences were packed with great sessions and talks. If I had to pick favorites from last week’s presentations, I would have to opt for Iván Sánchez presenting his latest projects, including what3fucks and geohaiku:

6 – Iván Sánchez Ortega, Mazemap – Addressing NSFW Geodesic Grids from krokskogstrollet on Vimeo.

Followed closely by the impressive project presentations of the student organizers of FOSS4G-NOR:

10 – Program Committee – What are the results when students use Open Source? from krokskogstrollet on Vimeo.

All three projects: OPPTUR, GISTYLE, and the flexible traffic web viewer were great demos of what can be achieved with open source tools. Mathilde’s GISTYLE project is also available on Github.

An inspiring GISummer comes to an end, but with so many videos to watch and workshop materials to explore, I’m convinced that the autumn will be no less exciting.

If you want to become an active part of this year’s FOSS4G, it’s now time to start thinking about your contributions!

FOSS4G 2014 will be taking place in Portland, Oregon, USA from Sept 8th-12th. Like last year in Nottingham, there will be a regular track for presentations as well as an academic track and a series of workshops.

FOSS4G 2013 in Nottingham is history. It was my first FOSS4G and a great event. Meeting so many people for the first time in person is really exciting. I had the great chance to present some of the work I did at AIT on comparing street networks. If you couldn’t make it to the conference or missed my talk, here’s the chance to hear it again:

(Tip: You’ll find many more FOSS4G presentations on Youtube.)

Slides and the paper are listed on my publications page. If you are interested in the code, you can find it on Github.

So far, I couldn’t find Tim Sutton’s QGIS keynote video on Youtube. Maybe it will be uploaded later. In the meantime, you can enjoy his slides.

Of course, you already know that the release of QGIS 2.0 was also announced at FOSS4G. In case you haven’t seen the great list of new features yet, have a look at the visual changelog.

The results of the FOSS4G 2013 map contest have also been published now. Thanks to everyone who voted for my entry “FLEET Taxi Tracking” which made it to Runner-up: Best Anti-map Map!

It’s almost here, the biggest open source GIS event of the year: the FOSS4G 2013 in Nottingham. It’s going to be my first visit to FOSS4G and I’m looking forward to present a project I did together with two colleagues at AIT where we compared OpenStreetMap to the official Austrian street network using tools developed in QGIS 1.8 Sextante. The presentation is scheduled for the first day and it would be great to meet you there:

I also have the honor to present Victor Olaya’s Sextante/Processing in a workshop together with Paolo Cavallini on the 20th:

I guess I owe Victor a geobeer or two ;-)

See you in Nottingham! And for those who can’t make it to the UK: I’ll try to keep you posted if the conference wifi allows it.

For all of us who couldn’t attend FOSS4G in Barcelona this year there are some of the great workshops available online:
