idea extracted from #385

If you expect others to implement it, you need to be a bit more forthcoming: What should the Overpass query look like, what should the design look like etc pp.

after attempting to implement this quest at start for my fork I discovered that the scale is too detailed to ever fit into SC quest

at least I see no way to do it properly

[westnordost]

What do you mean, too detailed?

[matkoniecz]

Yes, with wiki description at https://wiki.openstreetmap.org/wiki/Key:sac_scale#Values I was unable to classify a route that I remembered well.

And given that I am still stuck with answers to parking access quest as being not a good enough to make PR, I would not expect a success here.

I don't think it's too hard to classify sac_scale, we can add photos from the wiki. If we are asking for smoothness, we could also ask for sac_scale, which in my opinion is easier to classify and sac_scale would be highly beneficial for hikers. I think we should reconsider this.

If we are asking for smoothness

Note that smoothness quest was already at the limits of what could possibly be supported, and it required huge amount of work to make it suitable for SC.

And yet, whole of smoothness is just one (smaller) point of several in the matrix (like trail, use of hands, terrain, steepness, danger, equipment/skills required are some of the others) needed to properly determine sac_scale.

It is IMHO significantly more complex than just photos... Especially ones resized to just a part of (already tiny!) mobile screens!

As a survivor of "scramble" community thread for example, I'm too not feeling confident that average SC user would be able to verifiably identify sac_scale (even if we somehow managed to present them that whole identification table from the sac_scale wiki without overwhelming them), unless there happened to be official sign with SAC T1-T6 markings posted on the trail.

Importantly, StreetComplete Quest Guidelines (among other things) say:

• 👨‍💻 Users are no experts: No knowledge about OpenStreetMap or any other background knowledge must be necessary

For tagging sac_scale, I'm afraid that both mountaineering experience as well as knowledge of OSM wiki definitions (as many regions use other different scales/rating systems, see the thread above) might be required.

That being said, what might be interesting to you @michalgwo is SCEE (StreetComplete "expert edition").

It already allows one to add custom tags (like sac_scale) manually to ways (so solves your need, albeit not in most user-friendly way - you need to enable expert mode first); but also it does not balk at required domain expert knowledge as prerequisite for solving quests, so it should be significantly more open to such quest if one were to suggest it.
You can have both SCEE and regular StreetComplete installed simultaneously if you want to try it out.

I hope one day this and other hiking related keys will be StreetComplete quests, but I think we should wait until this discussion will lead to an accepted proposal.
