All our maps include Pistes (where mapped on OSM) and have done for some time; these are named (where that data exists in OSM).
The maps now also display the grades/difficulty of them, where that data exists in OSM. This data is appended, between square brackets on the Piste name or on its own where no Piste name exists. E.G. 'Flight [Advanced]' or '[Easy]' respectively.
See the screen shots below:
This rating system is the same for Alpine, Nordic, Ski-tour, Sled and Snowshoe; where Novice or Easy are the least challenging/technical routes/pistes, and Extreme is the highest or most demanding/difficult.
The way that Pistes are shown has now been updated, more details can be found in the blog posting, here: https://talkytoaster.me.uk/updated-piste-rendering/
