I think we can at least add an image tag as a raw data for someone such as wheelchair users or mapillary that may estimate the height automatically in the future :) lowered: https://www.openstreetmap.org/node/4294717996 raised: https://www.openstreetmap.org/node/4293918233 Shu Higashi 2018-01-08

Not, it's not ideal, you are right. It's just an idea to create some order, because the current kerb scheme isn't ideal either. Even if only three out of four wheelchair users were satisfied with `mountable`, `semi-mountable` and `non-mountable` this would be a step forward, in my opinion.

I like the idea of explicitly indicating the presence of a ramp, as they're specialized infrastructure that isn't exactly the same as just having a sloped curb interface. Though I would argue that it makes sense for them to be a linear feature separate from the `kerb` key, as they have non-trivial

a 2mm kerb (the last picture) is imho a lowered. I don't see what value added would bring the fact that the angle of these 2mm is square. for me it is necessary to remember the purpose of the tag: accessibility. if all profiles pass this kerb without a problem, it's lowered. the problem is for

I agree that `kerb:height` is more useful than `kerb`. However, `kerb` seems to be a good starting point when mapping many kerbs and you can't measure them all yet, as it gives a rough information whether most wheelchair users can cross the street there or not. The question is: does it make sense

I'd use "normal" or "regular", leaving "raised" for "above the norm". Both values are quite rare, but I guess that is because most will simply not tag it. Or (as the wiki discussion suggests) use kerb:height in cm. Looks like that wiki page could use updating... Matej Lieskovský On 28 December

kerb=raised is a bit subjective, but you can always add kerb:height when in doubt. Another way to look at it is as the shape at the interface: flush = straight on, lowered = approaching linearly at an angle, rolled = rounded, raised = square edge. On Thu, Dec 28, 2017, 12:15 PM Selfish Seahorse
