FOSS4G Conference

I am very much looking forward to participate in the 2016 FOSS4G conference taking place in Bonn, Germany this year. FOSS4G is one of the conferences I try to participate every year because I really like the spirit of the Open Source Geospatial community that gathers on this international conference series once a year during the dog days. My first FOSS4G was 2010 in Barcelona, then I was in Nottingham 2013 (my blog post about 2013 FOSS4G), 2014 I also attended at FOSS4G in Portland, about which I also blogged. So this year will be my fourth FOSS4G participation! And best is, it will be just around the corner from my home town Cologne, so I can stay at home during the conference and do not need to book travel and a hotel, which is quite weird for participating in an international conference :), but also quite comfortable and indeed cost saving. I will give two talks and will chair one session, on which I introduce some details in the following.

PaleoMaps talk

My first talk will be on the first day of the conference, Wednesday 24th August, 15h at the Fireplace Room. The talk will be about a new project we started within our Collaborative Research Centre, titled PaleoMaps: SDI for paleoenvironment GIS data". Strikingly (to me), the talk has the ID #555 in the conference system :). Here is the abstract of the talk:

Paleoenvironmental studies and according information (data) are abundantly pub-lished and available in the scientific record. However, GIS-based paleoenvironmental information and datasets are comparably rare. Here, we present an OpenScience approach for collecting and creating GIS-based data and maps of paleoenvironments, and publishing them in a web based Spatial Data Infrastructure (SDI),for access by the archaeology and paleoenvironment communities. The Open Science approach to the publication of data, allows to properly cite the published datasets as bibliographic sources in research that builds upon these data sets.This paper has its focus on the implementation and setup of the Free and OpenSource Software for Geospatial (FOSS4G) based SDI, and on the workflow for compiling and publishing the GIS data.

I submitted the talk for the FOSS4G Academic Track, on which I also volunteer as a reviewer and as a Track Editor, about which I will explain further below some more.

Semantic MediaWiki @ OSGeo Wiki talk

My second talk will be on the second day of the conference, Thursday 25th August, 12h in the Plenary Office. This talk is about my endeavours to improve the OSGeo wiki for collaboratively storing and handling structured information and data. The talk is titled "SMW @ OSGeo Wiki – How semantics improve the wiki and facilitate a collaborative database for OSGeo". Coincidentally, the talk has the ID #111, which also bugs me a bit :). The abstract of the talk is given in the following:

Recently, the OSGeo wiki was updated from an ancient version to the current LTS release of MediaWiki. This update broke the functionality of the first OSGeo wiki usermap implementation, dating back to 2008. The map shows the location of OSGeo members on a web map integrated into the wiki. A new version of the usermap [1] was implemented based on Semantic MediaWiki (SMW) [2] to replace the first usermap [3]. This presentation will describe the new features and possibilities that SMW adds to the OSGeo Wiki. After a short introduction to SMW, based on the OSGeo member model, that recently replaced the old usermap, a basic data model and its use in the wiki, as well as major features of SMW are explained. The data model development approach, using mobo [4], applied for implementing the OSGeo Members map will be explained briefly. Additionally, simple examples for bootstrapping smaller semantic models are given too. The presentation concludes with ideas for further applications of SMW in the OSGeo wiki, like the already implemented Advocate and Board lists pages, as well as possible applications, for example a collaboratively maintained OSGeo/FOSS4G service provider directory, or even a collaborative open geospatial data directory are proposed or suggested.

Session Chair

I also volunteer as Session Chair on the third day of the conference, Friday 26th August, Tunnel. The session will host two very interesting talks by well known members of the OSGeo community. The first talk will be given by Pirmin Kalberer on "Using and extending GeoPackages". And the second talk will be given by Sean Gillies on the topic GeoJSON and the IETF.

Academic Track

Additionally, I volunteered for organizing the Academic Track, together with Franz-Josef and Pradeepkumar. I was involved in three paper reviews as a reviewer, and in seven contributions as Track Editor, assigning reviewers and overseeing the review process.


I am sure, this will be a great conference. It will take place at the newly opened World Conference Center Bonn (WCCB), which is build around the former German Bundestag building, including the former Parliaments Plenary Chamber and further facilities of the Bonner Bundestag. It will be a great experience to meet at this historic, and also architecturally interesting place. As said, I am really looking forward to experience this special place, as well to meet all the great people of the Open Source Geospatial community.
