I recently started converting the Iowa and Minnesota county borders
from simple ways to correct boundary relations, which means also
removing the doubled ways the adjacent areas share.
So far, so good, but I encountered some questions:
Shouldn't county borders always coincide with state borders? In the
case of the Minnesota/Iowa border, there were often differences up to
150 meters. I then used the state borders as the 'better' solution and
extended/capped the county lines. What would be the best way to do?
compare the sources of the borders. there are known issues with the USGS
county border data,
the borders in Tiger are much better.
