The Walkabout: London Complex Intersections | Pedestrian Mapping Initiative

The sidewalk:<side>= (I will refer to as “sidedness”) schema is objectively better than the sidewalk= (I will refer to as “old”) schema:

• Removes the possibility for ambiguity (sidewalk=yes and sidewalk=separate both are necessarily ambiguous with respect to communicating sidewalk presence by side)

Those ambiguous tagging variants don’t exist in Greater London. I’m pretty sure that @RedAuburn and I made sure of that.

@UW_Amy_Bordenave

Allows for much more flexibility (sidewalk:right=no+sidewalk:left=separate cannot be reduced to a sidewalk=* tag without losing information)

True, and I’ve only used it thousands of times before. It’s still completely and utterly irrelevant to replacing sidewalk=both with sidewalk:both=yes and doesn’t answer my question about whether this change is an editor driven “upgrade” or not.

@UW_Amy_Bordenave

Enjoys support from powerful and widely used editors such as StreetComplete/SCEE

Except that they will write sidewalk=both, sidewalk=left and sidewalk=right where that’s more concise. You could have checked yourself.

@UW_Amy_Bordenave

Even if you oppose separately mapped sidewalks, the sidedness approach for roadway tagging of sidewalks is clearly superior to the old schema.

No, but as I actually use pedestrian routing when planning and sharing running routes in London, I oppose people doing it badly. It’s almost as annoying as tedious whatiffery.

Additionally, they link to a video by @geocruizer which explains how to use approved street-level imagery sources to map pedestrian infrastructure.

This is the same user who repeatedly mis-tagged unmarked pedestrian crossings in the UK which were next to give way markings as crossing:markings=dashes and doesn’t respond to changeset comments or clean up their mess? This does not fill me with confidence. In any case, if you can’t recognise the UK’s give way road markings for what they are, you probably shouldn’t attempt to map highways in the UK from aerial imagery.
