Ski areas
Where Snowpace's list of places comes from, how it's kept current, and how a place gets fixed.
Where the list comes from
OpenSkiData publishes a list of the world's ski areas, built from OpenStreetMap and, for areas nobody has mapped there, Skimap.org. Snowpace keeps the named, operating areas in North America, with their location, base and summit elevations, and what they offer.
Activities
The list knows two kinds of skiing: downhill and nordic. Snowpace counts nordic as both classic and skate, and for now assumes snowshoeing is possible everywhere, because the list doesn't say. So a place can show snowshoeing without marked trails.
Keeping it current
A copy comes with the app, so it works on first launch and offline. After that, Snowpace downloads a fresh list at most once every 30 days, behind the loading screen ("Ski area listing"). If that fails, or the download takes longer than 60 seconds, it keeps the list it has and doesn't try again for 24 hours. A correction made at the source reaches the app within about a month.
When a place is missing or wrong
See A place is missing or listed wrong. Snowpace can't edit the list itself, but anyone can correct OpenStreetMap or Skimap.org.
