[OSM-talk] Highway tagging in the USA

[Peter Miller]

Ok I get the message re colours...

The question for the US at the moment then is how the define the OSM
hierarchy of road classes in a US context. The current tagging rules seem to
leap from trunk or motorway directly to tertiary. As a Brit I will stay out
of that discussion but will check to ensure that I can understand the
resulting rules and that they seem to work.

I do think we should consider retagging all the major routes (motorways or
trunk routes - to be advised) that were originally tagged as secondary in
the tiger import (but which have motorway-link tagged ramps). Otherwise we
are expecting Newbies in an area to immediately start retagging what is
there which might be seen as a bit alarming.


Regards,




Peter
