<div dir="auto">I'm assuming we're talking about unclassified roads (tertiary and unclassified in osm speak). The colouring seems to correspond to wider through roads similar to how they are differentiated in the (non-osm compliant) 1:25k Explorer/Landranger. Thus, it broadly aligns with the osm distinction between unclassified and tertiary Highways. It's not 100% consistent locally though, a ground survey should always be preferable.<div dir="auto"><br></div><div dir="auto">I'm fairly sure they don't factor in internal local authority classifications like C- numbered roads.</div><div dir="auto"><br></div><div dir="auto">Kind regards,</div><div dir="auto"><br></div><div dir="auto">AdamĀ </div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sat, 10 Dec 2022, 13:04 Dave F via Talk-GB, <<a href="mailto:talk-gb@openstreetmap.org">talk-gb@openstreetmap.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi<br>

For OS OpenMap Local do road colours represent their class or width?<br>
<br>
Has anyone seen a key/ symbols diagram for it?<br>
