feedback on gaia winter topo
Answered
I noticed a few glitches in the gaia winter topo rendering:
Where a ski trail coincides with a hiking trail or a road on the same way, the rendering should use "piste:name" rather than "name". This occurs frequently with XC ski trails in my area. A good example of this is Callaghan Lake FSR / Mainline XC trail at Whistler Olympic Park (OSM way 205875814). I think this discrepency should be easily resolved by choosing the piste:name name for winter rendering if it exists.
Where a backcountry ski (piste:type = skitour) route relationship overlays a way tagged for XC skiing (piste:type = nordic), the rendering sometimes shows only the backcountry ski route and not the underlying XC trail. In some cases I am seeing different results in the IOS map and the gaiagps.com map. Trails shared between XC skiing and snowshoeing using a route relationship appear to have this issue as well.
piste label rendering is inconsistent (sometimes black, sometimes by the difficulty of the piste, sometimes with or without a white halo).
Finally it looks like the map was rendered with a database that is at least a month old, because the edits I made after rerouted a popular ski trail in my area in October have not been included.

Hi @es.ee.nelson,
Thanks for the feedback, I've shared it with the map team.
Can you share an example location of your second issue where you are seeing differences on the Gaia Winter map on iOS and the website?
Right now both name or piste:name should work.
And sorry about the delay in OSM updates, we are working on an issue with the updater. We hope to have that updated again soon. -
If the data isn't current that's a big concern

It looks to me like the "piste:name" is never used, even if the "name" tag is unused.

I think I was wrong about the IOS vs web map difference - I think it was just different zoom levels producing a different rendering. Regarding name and piste:name, here is an example location:
https://www.gaiagps.com/map/?loc=15.1/-123.1487/50.1448&layer=GaiaWinterRasterMeters
OSM way 914874452 (https://www.openstreetmap.org/way/914874452) has name = "Callaghan Lake FSR" and piste:name = "Mainline". Mainline is the correct XC trail name but the winter map renders "Callaghan Lake FSR".
And here is an area that has ski runs tagged with piste:name only, and no names are rendered:
https://www.gaiagps.com/map/?loc=14.4/-123.1993/50.0373&layer=GaiaWinterRasterMeters
For example this OSM Way: https://www.openstreetmap.org/way/255627283

@es.ee.nelson, thanks for the additional detail, I'll bring it to the team.

I see that the winter v2 topo is now published on the website. The issue of giving "piste:name" priority over "name" still hasn't been solved, nor has the issue with the name being rendered in the wrong colour. I think the colour issue may be related to the name problem, since the location where I see this problem also doesn't override name with piste:name.

Also the "new" winter topo is being rendered with OSM data that is at least 4 months old.

piste:name priority is still not fixed. See https://www.gaiagps.com/map/?loc=15.5/-123.1527/50.1522&layer=GaiaWinterRasterMeters,mountaineering,GaiaTopoRasterMeters. "Callaghan Lake FSR" should be rendered with the name "Mainline" because that is the piste:name tag.
