But that's a different issue.
That some 'B' roads now need re-classifying and the alternate currently unclassified roads need upgrading on the council records is the distinction here. Routes through residential areas which are currently classified are being restricted with traffic calming, 20MPH limits or even barriers and alternate routes being improved, but the only documentation on that in the absence of new maps is the minutes of council meetings rather than as yet, the NSG or other council documents. Only primary and main routes get well documented re-designation currently :( In this case we do have to map what is on the ground rather than trying to justify the 'legal status' of those roads. Now if the three equally important secondary idents are treated with the same level of importance, then the addition of other restrictions will make more sense, rather than promoting a 20MPH 'B' road over a 60MPH 'unclassified' ... which the current rendering is doing? -- Lester Caine - G8HFL ----------------------------- Contact - http://lsces.co.uk/wiki/?page=contact L.S.Caine Electronic Services - http://lsces.co.uk EnquirySolve - http://enquirysolve.com/ Model Engineers Digital Workshop - http://medw.co.uk Rainbow Digital Media - http://rainbowdigitalmedia.co.uk _______________________________________________ Talk-GB mailing list Talk-GB@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-gb
