While in Schaumburg recently, I found the TIGER import data to be woefully incorrect. Most of the road geometry was no where near the real locations. It was sometimes difficult to figure out which road segment was supposed to match up with the real roads on the ground while looking at Potlatch with Yahoo imagery behind it. Our CANVEC data is of a slightly higher quality, but still could do with alignment in most cases that I have seen. No one data set is perfect, each one has it's own set of issues.
