|Used to define how a piste is prepared.|
|Used on these elements|
|Tools for this tag|
|piste:grooming||classic|| Groomed for classic style nordic or downhill skiing. If omitted for sledding runs (piste:type=sled) it implies groomed as "natural luge(sled) track".
Default value is assumed if piste:grooming is omitted.
|piste:grooming||mogul||A piste:type=downhill groomed for Mogul skiing (Buckelpiste)|
|piste:grooming||skating||Groomed for free style or skating||\/|
|piste:grooming||classic+skating||Both classic and skating. (For unknown reasons this wiki page proposes to use classic+skating although the default seperator for multiple values in OSM is the semicolon. "classic;skating" is in use as well.)|||/|
|piste:grooming||scooter||Classic style groomed by a smaller snowmobile, which means that the piste is often much looser and single lane.|||!|
|piste:grooming||backcountry|| Off-piste cross-country skiing, often referred to as "backcountry touring", where tracks are made manually by skiers.
Use with marked, cleared, ungroomed ski trails.
Use with often used, ungroomed sledding trails.
Many providers of ski preparation data draw a line between tracks groomed by wikipedia:snowmobile, and larger wikipedia:snow grooming vehicles that produce cross-country ski-trails conforming to FIS standards (reference needed).
Discussion issue: There may be a need for a tag to specify the gap between the skis in a classic nordic ski track (NOR: sporlegger/sporbredde), such as (piste:grooming:trackwidth=15/17/22/adjustable [cm]. Background for this: Skiforeningen, the Norwegian (Oslo-area) grooming organization are starting experimentation on user preferences. At Sjusjøen, they are also conducting experiments, and will build a groomer that can set different widths uphill and downhill.
