Great analysis - I did something similar for Arkansas, but it was
statewide and not county by county. I concur with your analysis - we need
to retain interstate and US highway edits where global routability has been
created. Approaching it on a county by county basis is a good plan also;
that will give us a chance to stitch up the county borders on all roads this
time as counties are updated. That will be a HUGE project - keep in mind
that some *major* interstate routes have finally been converted to dual
carriageway just last week.
As far as how to approach the TIGER 2010, some advanced conflation tools
will be needed / welcome. Something that can produce just a Geo-Diff set
of data, or allow virtual tracing over the new information as required.
I haven't seen the data, so I can't guess what can be done, but since I have
extensively modified my area, I envision just doing adds / deletes, and if
they have updated old stuff with actual county centerlines, I can replace
just areas created from "back of napkin style" geometries that you have seen
in your area.
