Hi everyone<br>
<br>
I'm at home recovering from dental surgery, so I've had the
opportunity to get a lot of imports done. But I've been importing
along the US border alot, and have ran into some trouble with TIGER
Data and need some advice. My problems are as follows:<br>
<br>
-Importing near the geopolitical oddity know as the <a
href="https://secure.wikimedia.org/wikipedia/en/wiki/Northwest_Angle">Northwest
Angle</a>, I encountered a disagreement about the coastline of The
Lake of the Woods. Canvec and data ends 150m north where TIGER data
begins. (thought they are both roughly on the same Longitude). An
inspection using Landsat and some surprisingly decent Bing imagry
strongly favour Canvec and show the TIGER boundary to be full of
twists and lagoons that don't appear to exist. How to I reconcile
this? The Canvec boundaries appear to follow the exterior edge of a
white surface that Canvec calls wetland, but may be ice. Sadly the
one place of this lake I know has no white surface nearby. <br>
<br>
-TIGER is full of duplicate nodes. When I run Validator to check
Canvec data I will often get 20+ duplicate node warnings from a
TIGER road I partially downloaded. I can fix this without
downloading the entire area of the way, but they I just hit more
ways with problems. <br>
<br>
Thanks<br>
