Wow, that is pretty ugly. The discrepency is there because the state border source has a lower resolution than the counties border source. What's odd is that in some spots, the county borders seem to follow land features correctly, but in other areas they don't (<a href="http://openstreetmap.org/?lat=40.658&lon=-76.7046&zoom=13&layers=B0FT">http://openstreetmap.org/?lat=40.658&lon=-76.7046&zoom=13&layers=B0FT</a>). This is a problem with the data source. We'll have to make a judgment call about what to do ...<br>
<br>Personally, I think the "look" of a map is less important having correct data, but I can definitely see the importance of having a visually-correct map.<br><br><div class="gmail_quote">On Wed, May 14, 2008 at 9:28 AM, Ted Mielczarek <<a href="mailto:ted.mielczarek@gmail.com">ted.mielczarek@gmail.com</a>> wrote:<br>

What data source did you use for this? Was it from TIGER? The borders<br>
don't seem to line up with the state borders (from TIGER) that we<br>
imported previously. It looks a bit messy. :-/ I've also noticed that<br>
the borough boundary I imported (also from TIGER) for my town doesn't<br>
line up with the county borders at all:<br>

The borough border seems to match reality a little better (the river<br>
is the county and borough boundary).<br>
