Mapper since: July 11, 2010
Keen on outdoor and Open-Source software, I have found both worlds in that project. And I am always cycling around with a GPS and camera or smartphone.
Please contact me if you notice an error or something so I can learn from my mistakes.
I made a Luxembourg extract, but there are some known issues with some borders. The latest file can be downloaded here and opened with JOSM.
Have a good day (:
