<div dir="auto">barrier=kerb was/is mainly a linear feature.<div dir="auto">kerb=* is mainly used as node, most likely originally as attribute to pedestrian crossings tagged as nodes on the crossed highway. With the more detailed mapping of crossings it has been used also as node with only kerb=* at the position where the kerb crossing footway hits the kerb. Some mappers then added barrier=kerb ro these nodes, which is in my view redundant, but not wrong.</div><div dir="auto"><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, 7 Jun 2021, 09:42 Mateusz Konieczny via Tagging, <<a href="mailto:tagging@openstreetmap.org">tagging@openstreetmap.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
