Openstreetmap passed its 100'000th km of nordic ski pistes !

This happens on 15.11.2022, somebody mapped the 100’000th kilometer of nordic ski piste. screenshot.

These are the trails tagged piste:type=nordic. They describe several practices : backcountry touring, classic style on prepared rails or skating on large groomed pistes. In OSM, they are distinguished thanks to the key piste:grooming=backcountry/scooter/classic/skating or classic+skating.

That’s pretty cool!

Thank for the news 😇👍🎉🎉🎉 How did you do to “raise an alarm” when this goal was achieved? Did you make a query via overpass (I don’t think so)? Or did you sum up all the length by scanning the OSM planet files? Or query a database?

Also what are the next “goals” you are waiting for? How did you come up with this great idea of looking for ski track length? 👍👍👍👌

Oh I look again the picture. Maybe you visited OpenSnowMap and just were lucky to find this???

Yep, just updated my signature on the diary to make things clear.

The stats at are updated daily counting ways length in the rendering database. This counts both ways and relation with piste:type=nordic, but removing duplicates (meaning a way part of a relation is not counted twice). It’s here: code.

I noticed a while ago that we were approaching a big round value, so I recently checked every day to make a diary entry of it ;-)
