[talk-au] sac_scale [Was: Deletion of walking tracks/paths]

[Andrew Harvey]

The awtgs= tag looks fine on it's own, a simple wiki page with basic info
about the tag would help people know how to use it and less likely someone
will misunderstand it like your German friend.

1. Would the tag be reserved for tagging officially assigned AWTGS values?
Or when not officially assigned a value left to mappers to decide the grade
value? If the latter, how would you separate those officially assigned from
those not? Perhaps awtgs:operator= with the organisation who assigned the
grade?

2. Does the AWTGS system apply more to routes than way segments? For
example a longer route loop might have a higher grade than a shorter loop
even if they overlap for parts. Would you then only apply AWTGS on a
route=hiking relation, or do you also tag on each way but only set the
higher grade to the parts of the walk which go beyond the easier shorter
sections (based on the example)?

The main reason I don't like the AWTGS is because it conflates
independent measures like surface, gradient, distance, navigational
difficulty, remoteness/preparedness. I think the ideally tagging system
would tag these attributes independently and then you could automatically
calculate an overall grade based on the highest value.
