[Talk-us] Highway tagging in the USA

[Peter Miller]

I thought it might be useful to have a concrete (literally) example of USA
tagging to talk about. So.. think I have tagged the highways from San
Francisco down to San Jose as described on the highway tagging page, with a
few exceptions. My reference was the international section of the highway
tag article:
http://wiki.openstreetmap.org/index.php/Highway_tag_usage#International_equi
valence

 

The exceptions are as follows:

 

1) I upgraded the Golden Gate Bridge from primary to trunk, but I think it
should be motorway because it has ramp-only access.

 

2) I upgraded most of the 'braided' highways in the San Francisco area and
other main arteries further south to primary. Some of the ones I coded as
primary in the San Francisco area have now been retagged as tertiary. I have
sent am email to the author of these changes to see if the motivation is to
get the roads to render yellow or if I have missed something.

 

3) IThere are many roads that are currently still tagged as residential
which should probably be tertiary, secondary or primary and there are of
course many areas of grey between primary, secondary and tertiary, however I
think it would be good to get some feedback and discussion first. Could
people take a look and see if I have got it about right and suggest or
execute changes where required.

 

Also. please could someone to a 'trial render' of the area using one or more
potential 'USA friendly' colour schemes so we can see what it would look
like. Personally I would be interested in something along these lines:

 

Orange and wide: Motoroway/trunk

Yellow and wide: Primary

Yellow at narrow: secondary

Fainted yellow and narrow: tertiary

 

Could this be done off-line and then posted as an image on the wiki for
discussion? Could anyone have a go at this?

 

Btw, I have been copying some emails from talk onto talk-us over the past
few days but they haven't made it onto the list, not sure why. Possibly it
was because I was not a member of the list (which I now am).
