FWIW, as the originating party for the “sidewalk as separate way” proposal, we have actually been mapping and tagging both the pedestrian crossing line geometry as well as the intersecting node geometry with the crossing demarcation.
Moreover, we highly recommend using the tag Crossing= exclusively for marked/unmarked tagging. The crossing=controlled tag should really be deprecated due to ambiguity in different locales and the fact that controlled isn’t mutually exclusive of the marked/unmarked designation. I believe both of the pages pointed to by Jack should be amended to clarify these points. Best regards, Anat @OpenSidewalks Sent from my mobile.
