Here are few resources for NC mapping:

Interstate Highways

Interstate Highways Relations

Interstate highways imported from TIGER data need a lot of fixing. It is probably easier to erase a section of the Interstate Highway imported from TIGER data and retrace it over the Yahoo! aerial imagery.

Here are some guidelines to consider:

• Separate interstate direction into two ways. For example, an interstate running West and East will consist of two parallel ways: one running West and the other running East.
• Apply the following tags to every way making up the interstate:
  • highway=motorway
  • name=I-40 East -- a verbose name that includes interstate's direction
  • ref=I 40 -- if more than one highway use the say way combine them using semicolons: ref=I 40;US 1
  • oneway=yes
• When the interstate runs over a bridge, add a way section with bridge=yes
• When the interstate runs through a tunnel, add a way section with tunnel=yes
• For exits leaving the interstate use the following set of tags:
  • highway=motorway_link
  • ref=364 -- reference in this case is the exit number
  • oneway=yes
• For the point at which the exit connects to the freeway, use the following:
  • highway=motorway_junction
  • ref=364 -- reference in this case is the exit number
  • exit_to=West NC 24; Business NC 24; To NC 50; Warsaw -- name should be the connecting roads or exit name as written on the sign, separated by semicolons. See exit list, using NC for state highways, US for national highways, and I for interstates as prefix, and designating the direction of the connecting highway when applicable.
  • name=Mid-County -- Optional exit name. Most exits do not have names. For an example of a named exit: Pennsylvania Turnpike

State Route

Major issues to watch for when editing TIGER data:

• Many exits imported from TIGER data are tagged as highway=motorway_link which is incorrect. They should be retagged as highway=primary_link.
• Direction of many exit ways are also wrong.
• Bridges are not tagged.

State highway attributes:

• • highway=primary
  • name=United States Highway 64 -- a verbose name that includes interstate's direction
  • ref=US 64 -- if more than one highway use the say way combine them using semicolons: ref=I 40;US 1
  • oneway=yes -- when the highway is divided into two ways.
• For exits leaving the highway use the following set of tags:
  • highway=primary_link
  • ref=7 -- only if exits are numbered
  • oneway=yes

Eastern Band of Cherokee Indians

Eastern Band of Cherokee Indians (EBCI) is located in western NC, the Qualla (land trust recognized by US Federal government) consists of 5 counties: Cherokee, Graham, Jackson, Swain and Haywood. Road naming should follow BIA section of US road tagging guideline.

Currently there are two kinds of road numbers:

1. BIA: e.g. BIA-12345
2. FED: e.g. FED-98765

FED- road is sponsored and constructed by Federal-Aid Highway program (FAHP). Please tag FED- road as ref=FED-{number}

Mapping Resources Available

NC Onemap Orthophotography

This is available as an imagery layer in JOSM. In the Outer Banks area, it differs from bing imagery by about 5 meters. I am unsure whether bing or the NC Onemap is offset or both.

I checked the imageries around Pilot Mountain, and found that Bing has a slight offset compared to NAIP and NC Onemap Ortho, so I recommend using the combo of NAIP and NC Onemap Ortho, to make sure you're all good. NAIP is the most accurate of all imageries, despite its low quality. But! Sometimes NAIP is newer, so i recommend redoing roads from there(In Pilot mountain State Park on NC ortho there is no roundabout, on Bing and NAIP there is) Ottwiz (talk) 10:31, 21 August 2021 (UTC)
