I'm a software engineer working (and living) in Helden (51.321,6, OSM map, g, mq, mm, wll, what?), in the south of the Netherlands. You can send me a note from the OSM page.

My mapping

I started out mapping the A73 motorway but after the AND import this was not required anymore. So I switched to all the old tracks I have stored. As I have a GPS since 2003 and usually always took it along everywhere I went, this is quite a lot. I'm still not finished with it. As I'm mapping my tracks, I also try to massage some of the ways that cross my path.

I'm also updating the town where I live. AND data is only on street level so a lot of features are missing (forest roads, streams, various amenities) and there are also new building developments.

Areas that I've mapped:

My gear



  • Mobile Action iGot-U GT-600


  • Garmin eMap
  • Garmin eTrex Legend
  • Adapt AD-850
  • Garmin Nüvi 205


I take my photos with a Canon Powershot A710i.
