About this data
Piste km: the length of each piste, measured once along its line on the map. Resorts usually advertise more, as they add itineraries, variants or wide pistes counted as several runs; and sometimes a piste is still missing from OpenStreetMap.
Data quality
Snowmaking and ski patrol are rarely tagged in OpenStreetMap — it doesn't mean they don't exist, just that hardly anyone maps them yet.
