I am busy preparing for two events: Only two days now until the State of the Map 2016 in Brussels, where I’ll be giving a talk about taginfo. On Sunday I’ll be hosting an Area Workshop where we want to talk about the effort to fix broken and inefficiently tagged (multi)polygons in OSM. I’ll be around for (part of) the hack day, too.

Last week I gave a talk about taginfo at the FOSSGIS 2015 conference. Thanks to the amazing video team all talks from the conference are available online in great quality. As always you can find my talk on my Talks page.

The next annual FOSSGIS conference on Open Source geographic information systems and OpenStreetMap will be held in Münster, Germany, from March 11th to 13th. I’ll be giving a talk there about taginfo.

Last weekend we had the SOTM-EU here in Karlsruhe. I had a lot of fun, but didn’t get enough sleep, something you’ll notice in the video from my Osmium talk. Oh well, not everybody can have their talk on the first day.

Next week the (German language) FOSSGIS-Konferenz takes place in Berlin. For the first time since 2007 I am not giving a talk there, but I’ll be around all three days to learn new things and (re-)connect with people from the OSM and Open Source GIS communities. Lars Lingner and I are also organizing a BoF session for freelancers. We both are have been seeing more and more interest in OSM and GIS development and services and are often contacted for projects larger than one person can handle or where different skillsets are needed. We want to better connect the freelancers in these fields to to able to help each other out. So if you are working freelance or have a small company in the OSM or Open Source GIS fields, please come join us on Wednesday for a chat.

On January 16 2014 I will give a talk about the OpenStreetMap data model at the HafenCity University in Hamburg. The talk will be in German. Everybody is welcome to attend, you don’t need to be a student there.

A few weeks back I gave two talks at the State Of The Map 2013 conference. One about Osmium, the other called “Towards an Area Datatype for OSM”. The slides and videos from both talks are now available on my talks page. Thanks to Peter Barth for “liberating” the videos from the 8 hour long flash-only videos put up originally.

Last week I was at the yearly FOSSGIS conference, the German language conference for Open Source GIS, Open Data and OpenStreetMap. This year it took place in Rapperswil, Switzerland near Zurich. I like the relaxed atmosphere and the good mixture of introductory talks and talks for power users.

The yearly FOSSGIS conference, the German language conference for Open Source GIS, Open Data and OpenStreetMap, will take place from June 12th to June 14th 2013 in Rapperswil, Switzerland near Zurich.

I gave two talks at the FOSSGIS 2012 conference last week. The first, OpenStreetMap in Zahlen und Karten, was not recorded and I will not release the slides as they will be difficult to understand and easy to mis-understand without my words. I will probably re-use the content for a few blog articles here in the future.

Next week is the FOSSGIS conference in Dessau. I’ll be speaking there about OpenStreetMap in Zahlen und Karten and Das Osmium-Framework. Together with Tim Alder I am also organising a community session to discuss the Wikipedia Multilingual Maps Project. See you in Dessau!

The Karlsruhe Hacking Weekend is over. 18 people were there at least part of the time. I had a lot of fun and even got a little bit of work done: As mention I worked on Taginfo and on the second day I worked a bit on the statistics for my upcoming talk at the FOSSGIS conference. I am using Osmium and full-history planet dumps to see what has been happening in OSM. I’ll publish some code and graphics at some point.

The Karlsruhe Hacking Weekend is in full swing. About 15 people are sitting around, munching apples, pizza and Gummi Bears and talking about things “somebody” should do “someday”. And we do some actual work, too. I fixed a few bugs in Taginfo, Sven and others are working on updating the German map style. Some people are talking about obscure Mapnik config options. No idea what the other people are doing.

Time for the next OpenStreetMap hack weekend. Hope to see you there.

Martijn van Exel is organizing a hack weekend on June 10-12 2011 at the Linuxhotel. I am planning to be there. After many hack weekends in London this ist the first such event in Essen after a long time. The first OSM event at the Linuxhotel was the Essen Developers Workshop I organized there four years ago. Has it already been that long?.

The organisers of the State of the Map Europe have published the programme and it looks very interesting. I will give a talk about Taginfo and a talk about Osmium, the two projects I currently spend my free time on.

Yesterday I gave a talk about Taginfo at the FOSSGIS2011 conference. The talk is in German, you can download a video (570 MB MP4). Many thanks to the volunteers who created the awesome videos of all the OSM talks at FOSSGIS!
