I can see that ski pistes are mapped with a line, but this does not give any idea how wide the piste ist. I think the ski piste should be mapped similar to large rivers, where the center line ist mapped and then the area covered with water ist also shown. Is there any way to map the width of a piste? The width is constantly changing alone the route. asked 08 Jul '18, 18:05  Amanning |
One Answer:
Yes, of course: Map the center line as a way with piste:type=downhill and also the area as a closed way piste:type=downhill and area=yes. Like here, for instance: http://www.opensnowmap.org/mobile.html?zoom=16&lat=45.39234&lon=6.6456 answered 08 Jul '18, 19:33  yvecai |
Thanks yvecai
I have never seen that done, but it is exactly as I thought is should be. Now I have got a lot of work ahead of me to map all the pistes around here.
For the record, I've also seen people mapping complex situations as multipolygons.
Although this is not the case in the above example from Les Trois Vallées, the closed way (area) should also have the tag name= (or piste:name=), with the same value of the linear way.
