This is a list of all activities in Belgium. Activities include mapping parties, social OSM gatherings, conferences of interest to OSM, ...

We have regular informal meetings, organized through Meetup [1] and published on osmcal. Not all activities are listed here. It's safe to check both and this page. You are invited to suggest meetups in your town!

We also have an irregular newsletter [2] where we announce events.

2015-04-25 Mapping party in Brussels - 9h till 13h

We are proposing a mapping party in Brussels on Saturday 25 April 2015, 9h till 13h.

The location for the meetup as well as for the work together is ESI École supérieure d'informatique . The address is : Rue Royale 67, 1000 Bruxelles. It is very close to Central station and the Federal Parliament. It has easy access by train (Central station), tram (92,93), bus (29,63,65,66), metro (Parc, Madou, Botanique) as well as by car on a Saturday morning.

The idea is to have a mapping party aimed at beginner mappers with the help of advanced ones, and to focus on improving Opencyclemap and Wheelmap. Everyone is welcome.

Are any of you interested in helping with the organization, the plan, the introductory talk, the advertisement everywhere (in newspapers, radio, TV ...) ... ?

Please fill out the survey on

The preparation could be supported by several Google Hangout meetings.


  • improve opencyclemap, a map for cyclists ;
  • improve wheelmap, a map aimed at everyone with special needs ;
  • take pictures and movies of routes, and everything on the way ;
  • take pictures of every MIVB/STIB/TEC/SNCB/De Lijn metro/tram/bus/train stops ;
  • report anything complementary interesting (street works, post boxes, shops ...)

In the afternoon we could experiment outside with Mapillary. Is there a place we could continue inside ?

Are there computer screens with HDMI input at our disposal ?

  • vul hier uw suggesties in


  • Gebouwen op een efficiënte wijze maken in JOSM gebruik makend van AddrInterpolation, BuildingsTools en Terracer. Er zijn nog een paar zwakke punten in dit workflow ivm. hoe Terracer punten (en dus ook hun history) verwijdert.
  • Het gebruik van associatedStreet in een industriezone of campus. Deze gebieden kunnen nog niet echt goed geadresseerd worden, en worden ook niet door Nominatim gedetecteerd. Mogelijk moeten we een voorstel doen om associatedStreet uit te breiden waarbij de 'street' ook een gebied mag zijn.
  • Scripting met Python in JOSM. We zijn er aan uit geraakt hoe een script te schrijven dat een tag kan toevoegen aan een node. Dit testscriptje zal ergens online komen, en nu dat de juiste workflow gekend is kan de syntax uit voorbeelden in andere talen (Groovy bvb.) gehaald worden (API blijkt tot zover identiek te zijn) en scripts geschreven worden.

  • kennismaking
  • huisnummers - potlach 2/JOSM
  • landuse en farm/farmyard/farmland/field


  • farmland is een duidelijkere tag voor farm, omdat sommigen voordien de farmyard aanduidden als farm
  • farmyard = "het erf" van een boerderij = stukje land waar de bedrijfsgebouwen staan
  • farmland = landbouwgrond

  • maandelijkse samenkomsten elke 1ste woensdag van de maand : volgende vergadering = 6 april om 19:30

2010-04-18: Mapping party Deinze, east-flanders

  • Type: Mapping party
  • Date: Sunday April 18th, 2010
  • Start time: 10h00 local
  • Location: Start at Deinze Railway station, finals at De Ceder (
  • Attended: kenny, ivo, ben, wouter, dirk, ivan, Almost forgotten Luc Speedy, karel

Party began with an extensive newspaper interview. And we did get newspaper coverage! De Gentenaar / Het Nieuwsblad

Unfortunately one person's GPS traces were lost through the miracles of technology. Fair progress was made but much remains to be done.

Cake diagram



  • Industriezone Europalaan
  • from Europalaan till village Machelen
  • Woonwijken Watertorenstraat & Molenpark

Still to be done

  • links from Petegem to the N43 road (Tonnestraat, Hubertstraat, ...)
  • Village Machelen (some footpaths there), and everything South and West from there

(( left here the previous text from the "upcoming" section ))

Some people in Eastflanders are planning a mapping party in April. The location would be Deinze. As far as OSM is concerned this is mostly terra incognita so it should be spectacular to go mapping there.

It's also easily accessed by train and by highway (E17). The date is fixed at Sunday April 18. A first start of the splitup of the territory can be found here (made use of the competition :)

We will meet at the station at 10am, gather tracks until 1pm, grab a bite and go to De Ceder ( where we will have a meeting-room at our disposal. Bike hiring could be done in for about 11€/day which is about the same thing as bringing it along on the train (9€ for a day pass; 5€ for one ride only). Please notify me if you are interested.

2010-03-28: Mapping party Turnhout

  • Type: Mapping party
  • Date: Sunday March 28
  • Start time: 10h00
  • Location: Brasserie't Stadspark, Parklaan 56, Turnhout. The site of the brasserie has a map here. Should not be too hard to find
  • Attended: eimai, speedy, ivom, mdeen, karel, kurt, filip wolters

A mapping party was held in the city of Turnhout and it's surroundings. Some zones were mapped, and after rain shower the party turned in a lively OSM-cafe meeting.

Cake diagram

Turnhout cake.png

The cake map is based on a tiny dataset, which contains a set of closed ways (waterway=river, name=3 for zone 3) and for each closed way a separate place=suburb, name=Zone 3" is used. The actual map is built by rolling the data through mapnik on top of a simplified base layer (basically streets and landuse).

The Garmin gmapsupp.img file contains two osm-data derived maps (base map + a maplint version) and the zones as separate maps created with MkgMap. The idea here is to be able to visit certain zones and stay within them. The idea was tried out during the mapping party and was useful for some Garmin users.


The resulting traces from the party you find on the right.

Nice evening. Good conversation, we even talked about OSM every once in a while :-). Data loggers, free software and different kinds of software for processing the traces and the pictures were also a topic, of course. It was good to get to know a few people in person.
