<div dir="ltr"><div>I've examined the data againnst aerial imagery and the Highways England positional data for VMS signs is so poor it really precludes an import which is sad. Signs are up to an estimated 10m away from their gantries and signs on the same gantry don't even line up. The Birmingham data might be better but it's difficult to check with aerial imagery as most of them aren't gantry-borne. I'm happy to chip away at this manually, unless anyine feels we can still go ahead with an import and then adjust the nodes manually- it will be a hard sell outside our group.<br><br></div>My proposed tagging is<br><br>

I'm not sure if these *need* treating separately but it may be worth doing so anyway. The car parks should be small enough to start with and will enable us to get a good grip of the data.<br><br></div>For short description the bits that seems useful is the sign size (e.g. 3x18) which I assume is rows and characters. In "M6/6054A" the M6 is obviously the road and I believe the "A" indicates which side
of the road it is on (see:
<a href="https://wiki.openstreetmap.org/wiki/Key:carriageway_ref" target="_blank">https://wiki.openstreetmap.<wbr>org/wiki/Key:carriageway_ref</a> ). Do you know what the "6054" means? Wait... found it! It looks like it is the asset reference for the structure that the sign is attached to. See for example:</div><div><br></div><div><a href="https://www.google.co.uk/maps/@52.4905635,-1.7319734,3a,15y,288.18h,88.53t/data=!3m6!1e1!3m4!1sgldMiJ0rpLi97FRlvR32CQ!2e0!7i13312!8i6656" target="_blank">https://www.google.co.uk/maps/<wbr>@52.4905635,-1.7319734,3a,15y,<wbr>288.18h,88.53t/data=!3m6!1e1!<wbr>3m4!1sgldMiJ0rpLi97FRlvR32CQ!<wbr>2e0!7i13312!8i6656</a><br></div><div><br></div><div>If all the motorway or trunk ones are like this then may put the "M6/6054A" bit in a tag such as gantry_ref=. <br></div><div><br></div><div> Do we know what "SPICE" means?
