[Tagging] How to tag sidewalk slides

[Nick Bolten]

The amount of time someone spent at an incline is important for some
pedestrians, so I'd use an option that splits the way and sets the incline
tag.

sidewalk=slide might be related to a tag I've wanted for a while. I think I
would personally call that a ramp, so maybe a use of a tag like ramp=yes
would be worth discussing.

There's two big benefits I can name right away:

- It becomes easier to incrementally map l to armchair map these features.
User A tags ramp=yes on a footways (armchair mappable), User B can then use
a QA tool and add incline=up/down (armchair mappable), user C can add
incline=a number (must map on-site).

- It becomes possible to distinguish infrastructure built as a ramp (like
this slide or a wheelchair ramp) from any other segment of footway that
just happens to be steep.

Does ramp=yes seem like an appropriate (hypothetical) tag for this
situation?
