Mapper since: October 07, 2011

I’m a german, retired software developer born 1966, a passionate cyclist (6000 - 9000 km/year) and I help with the maintenance of mkgmap (see ) since 2011.

My home area is mapped very well (thanks to others), so I first concentrated on QA,. I was esp. interested in reducing the number of typos in tags which affect routing. Since autumn 2015 I am (armchair) mapping in Japan, as this area is full of imported data with low quality. Since 2018 I also help with the development of JOSM.

Ich spreche/schreibe auch Deutsch, Texte in anderen Sprachen versuche ich mittels Web basierter Übersetzer zu verstehen.
