Allow tagging tactile_paving=incorrect for when only one side of a crossing has it

[peternewman]

Use case
It affects also crossing ques, but is no really correct when only one side has paving?

Probably incorrect is the right thing there. The wiki has "or if only one sloped kerb at a crossing has tactile paving" as an example of incorrect.

OT, but I'd appreciate some clarity/a new option for this (I normally just tag no as it's not yes). Also on a crossing with an island, if its only on either side but not on the island which is right?

There was a bit of a discussion here: #2738

I'd support having an other answers button of "Tactile paving only at the top or only at the bottom" and similarly for the crossing quest "Tactile paving only on one side" which would tag incorrect after a confirmation.

See also #2738 .

I appreciate incorrect is low usage currently (0.11%) but I don't know about others but I'd certainly have been tagging no when it's only on one side (given "Does this crosswalk have tactile pavings on both sides?") although I'm not sure how many of those I've had.

As mentioned I've also been tagging no if it's on the kerbs but not on the island as it's not on both sides of the two crossings, but I appreciate that probably needs a more general tagging discussion to find out what is the "correct" answer, or asking a blind person. @matkoniecz do you have contacts/feedback from your tactile maps?

Proposed Solution
Add an other answer for only on one side of the crossing

https://wiki.openstreetmap.org/wiki/Key:tactile_paving requests since 2010 to tag such cases with tactile_paving=incorrect. It seems strongly preferable to tactile_paving=no - lets imagine actual use. Blind person is navigating and gets info that the upcoming crossing has no tactile paving - and they encounter tactile paving from one side. It would be preferable to get info that tactile paving is incorrect. (I even started opening a new issue on StreetComplete tracker, then discovered #547 - I think that SC should provide =incorrect as answer available from "tactile paving on one side only". This situation is quite common in my area)

[westnordost]

Okay, so add the option "Only one side" and tag that as incorrect then?

[matkoniecz]

Yes.

In the past I answered this with 'no' (we have a lot of them here). Do we resurvey them, so a 'no' can be improved to an 'incorrect' over time?

[matkoniecz]

Resurveying all =no without considering their age makes no sense, but you can for example remove such tagging in your nearby area and map them again if you think that many were mistaken (JOSM and level0 are likely to be useful).

Or use Vespucci on noticing places like this to retag.

Tactile paving is resurveyed, for a "no" it's 4 years since last edit by default. If StreetComplete is set to resurvey more often it goes to 2 years.
