12 QGIS Developer Meeting in Essen 2014

Period and location

October 2nd-5th 2014, Essen, Linuxhotel (Germany). People can already arrive on Wednesday (1.10) late afternoon (6pm) and use the facilities in the evening.

Please note that the QGIS Developer Meeting starts on Thursday morning 2.10. and finishes on Sunday 5.10 afternoon. The reason is, that the Linuxhotel sponsors the event and they only have free rooms for this period and have to prepair their rooms for training courses starting on Monday again!

Essen is a city in the central part of the Ruhr area in North Rhine-Westphalia, Germany. Located on the River Ruhr, its population of approximately 579,000 makes it the 9th-largest city in Germany. For the year 2010, Essen was the European Capital of Culture on behalf of the whole Ruhr area. You find more information here: http://en.wikipedia.org/wiki/Essen

The Linuxhotel (http://www.linuxhotel.de) is one of the nodes for open source training in Germany. For years, they support open source projects financially as sponsor and/or provide space for developer and project meetings for special conditions (see: http://www.linuxhotel.de/community.en.html). The QGIS project is thankful that the Linuxhotel (Villa Vogelsang) will host and support the 12th QGIS Developer Meeting.

We currently have 3 supporters / sponsors for the event :

(http://www.linuxhotel.de/) - Venue, accommodation, drinks, etc at very reasonable conditions.

(http://www.fossgis.de/) - Support with 1500 EUR.

(http://www.gbd-consult.de) - Organization



We try to make it possible for all participants to stay directly at the venue. The Linuxhotel provides special conditions for open source projects (see http://www.linuxhotel.de/community.html). The maximum number of beds for the special conditions (including single and double rooms, all rooms) is at about 27. If necessary, they would also allow participants with sleeping bags, tents, etc, but we would not really recommend that. If there will be more than 27 participants, you find further accomodation nearby at a normal rate. So, be sure, there is a solution for that.

By train from Essen Main Station

You can buy tickets online at http://www.bahn.de/i/view/DEU/en/index.shtml

The nearest train station to the Linuxhotel is called "Horst S-Bahnhof Essen (Ruhr)" (S3). It is a 10 minutes walk away. The nearest train station with taxi waiting area is called "Essen-Steele". If you arrive from Essen main station at Horst S-Bahnhof Essen (Ruhr), then go under the tracks, up the hill, at the end right into "Lindkenshofer Weg". After 200m turn right again into "Eberhardstr.". This leads you straight to the brown wooden door of our villa Vogelsang. Also see figure: http://www.linuxhotel.de/pics/karte-s-bahnhof.png

By car

Nearby Autobahn/Highway exits are:

  • A40 Exit/Ausfahrt Nr. 27 "Essen-Kray"
  • A40 Exit/Ausfahrt Nr. 26 "Essen-Frillendorf"
  • A52 Exit/Ausfahrt Nr. 30 "Essen-Bergerhausen"

If you leave the Autobahn, drive in direction to "Essen-Steele" and follow the signs to "Essen-Horst". You will pass two super markets "Aldi" and "Lidl" and a level crossing. From the intersection Dahlhauser Straße/Von-Ossietzky-Ring in the center of Essen-Horst you will find signs to "Villa Vogelsang". Also see figure: http://www.linuxhotel.de/pics/karte-autobahn.png and http://www.linuxhotel.de/pics/karte-essen-horst.png.


  • Processing help files
    • image support
    • advanced help files format (zip with RST document and images folder)
  • Processing bugtrackers. We still have two separate bugtrackers for Processing, which is confusing for users and developers.
  • Core Python plugins and their dependencies. This mainly related to MetaSearch plugin, it was added without wide discussion and brings new dependencies into QGIS sources. We need a policy for such cases. There are at least two possible solutions for dependencies:
    • put all dependencies into QGIS core (as MetaSearch does)
    • make core plugins with external dependencies inactive by default and add note in their description
  • Merging QGIS context help and documentation
  • QGIS Documentation - how can we organize regular funding for keep english documentation up-to-date
  • QGIS Mapserver Python Plugins
  • New geometry model (Curved types, support mmsql standard)
  • Future of QGIS Web Client (migration to different client libraries)
  • QGIS financials
    • Donation handling
    • getting new sponsors
  • Discuss and plan next meeting in Denmark (Lene Fischer will be in Essen and would like to have a meeting on that)

Individual Preparation

  • Bring your own computer (and power supply!). Better with a power bar, compatible plug and long cable, and ethernet cable (we'll provide wifi, but better you have a cable, too).
  • Install git and the compiler tools, and come with a working QGIS development environment if possible.


  • Is the QGIS Hackfest just a coding event?
    • It is mainly a coding and documentation event. It is a working session for people who are already participants in the QGIS project and/or are committed to improving the QGIS project.
    • On demand we can do some presentations of current working qgis implementation and new upcoming features to spread the idea of openGIS software
  • Is the QGIS Hackfest for developers only?
    • No: anybody can help, with testing, checking out bugs and fixes, documentation and more.
  • Where can I get help and more information about the hackfest?
    • Contact Otto Dassau <dassau_at_gbd-consult.de>
