Bicyclist with GPS on board. My main interest here is to improve bike routing with an emphasis on highway tags (surface, smoothness, cycle lanes, maxspeed, give_way, access). Surface and smoothness, especially, mark the difference between ways suitable for road bike, city bike, or MTB. I try and set those tags on all ways I ride on.

While I’m surveying, I focus on road tags as outlined above. By-catch are benches, picnic tables, and playgrounds. I try tagging bus stops with wheelchair=yes/no if that’s obvious to me (wheelchair=no is typically very obvious, and very useful information to add; being sure of wheelchair=yes is harder).

Since fall 2020, I’m part of the BAG update team, maintaining the outlines and addresses of buildings in the Netherlands through import from a public government database (BAG).

Besides mapping, I dabble with developing JOSM preset files to simplify my life, see Maybe they’re helpful for other users, too.
