Skiing GPS Tracks
I've finally put online some GPS tracks I've recorded on a couple of occasions when I've been skiing, just for casual interest.
First there are a set of tracks from Serre Chevalier in 2007. I started splitting this one down into individual pistes and lifts and colour coding them accordingly, but ultimately I decided that life's too short and just dumped all of the tracks together.
The second set is from Alpe d'Huez in 2009, and I didn't bother mucking about with this at all.
The final set is the most recent and is from Tignes and Val D'Isere in 2010. It's a bit smaller than the others because I had battery issues and so didn't get tracks recorded every day.
The tracks don't necessarily represent every slope skiied, but they give an indication of terrain covered. They look fine in Google Earth but they don't work particularly well in Google Maps because there are too many tracks to fit on to one screen.
