[Talk-us] Best sources for boundary lines?

[Nathan Edgars II]

(note: I'm talking about boundaries that have stayed in the same place
during recent times, not those that change every year by annexations.)
While the TIGER data is pretty good for these boundaries, it has some
precision issues. For example, at
http://www.openstreetmap.org/?lat=40.81072&lon=-74.06072&zoom=16&layers=B000FTF
the line is shown following Paterson Plank Road over the Turnpike,
while USGS places it on the former pre-Turnpike alignment of the road:
http://mapper.acme.com/?ll=40.80869,-74.06204&z=16&t=T Other (probably
unusable) sources such as http://gis.co.bergen.nj.us/appbase/ and
http://www.state.nj.us/transportation/gis/maps/bergen.pdf agree with
USGS.

So the question is: for boundaries that have not changed since the
USGS topos were created, can it be assumed that they will be more
precise than the TIGER data? Are there any other usable sources that
will be more precise than TIGER?
