Hi, I'm trying to figure out how to export traces/tacks from a snowmobile map https://skoterleder.org/ which is OSM based but so far I haven't been able to. I've searched but was unable to find an answer to this question. Any ideas? Thanks for your help. |

I don't think you can. The tracks are drawn directly onto the PNG images (and not loaded separately into the browser where you could potentially save them as a file). The source for the tracks themselves is clearly not OSM, which means you cannot export them from OSM either. So you'd have to talk to the makers of the site and ask if they can give you the data. 1
Actually, the site itself says (click "mer information" and then "förbättra kartan") that the way to get new trails onto the map is to add them to openstreetmap, using snowmobile=yes or snowmobile=designated, depending on the status of the trail.

It appears you are right. I have seen some tracks on the map that were criss-crossing an existing road in OSM and I thought these must clearly be GPS tracks and cannot come from OSM, but indeed even those are in OSM as snowmobile tracks! Apologies for the mistake then - you should be able to export them in Overpass, e.g. http://overpass-turbo.eu/s/EO9

Snowmobiles are sort of inverted to ordinary vehicles under Swedish law — while it is illegal to drive “normal” vehicles off road, it is illegal to drive snowmobiles on (public) roads (there are sometimes explicit exceptions to allow access to things like petrol stations). This can probably explain some crisscrossing. =) (Though it might just be sloppy mapping, of course.)

Thanks for your help. With Overpass I can extract the tracks and colorcode them as I like. I then used a tool called IMGfromGPX to convert the tracks (exported GPX file from Basecamp) to an overlay map file for my device. |
