|Tools for this tag|
Intended to describe the preparation of a piste dedicated to winter sports. The tag and its values depend on the type of piste it is applied to. The grooming is generally applied to ways rather than relations, as it is a characteristic that can change along the piste.
Alpine or downhill
Can be omitted, this is your standard ski run mechanically groomed by a tracked vehicle.
A piste:type=downhill groomed for Mogul skiing (Buckelpiste)
The term 'backcountry' can be misleading, here it just means 'un-groomed', nothing more. For these runs, it is important to specify patrolled=yes or operator='Resort name' if the piste is part of the official pistes of a resort or patrolled.
Nordic or cross-country
Two rails for classic style nordic.
piste:grooming=classic;skating / piste:grooming=classic+skating
Wide piste for skating and at least one set of classic rails. While the semicolon is the common value separator in OSM, classic+skating is used more often (ca. 31,000 times as of December 2021) than classic;skating (ca. 19,000 times).
Wide piste for skating (or 'free') style nordic.
Classic style groomed by a smaller snowmobile, which means that the piste is often much looser and single lane.
Un-prepared itinerary for cross-country skiing, tracks are made manually by skiers.
Winter-hiking or snowshoeing
A mechanically groomed piste that can be hiked with simple boots or can be used for running (default if grooming is absent).
Requires snow shoes.
A mechanically groomed trail, signposted by its operator. This happens for instance when a resort downhill piste can (is allowed to) be used for a skitour ascent.
Rough itinerary for cross-country touring, no operator to lay the track (default if grooming is absent).
Implies groomed as "natural luge(sled) track".
Use with often used, un-groomed sledding trails.
