Fort those of you who followed the APRS Sig thread about Tiger
inaccuracies a couple of weeks or months ago, this is a significant
deal. I may want to snag the shapefiles; I'll get ahold of the player
in NYC who was so concerned about the TigerLine files. This should make
him happier.
One caveat: It is my understanding from our USGS State Mapping
Coordinator that not all of the SDTS coverages have been appropriately
reprojected to NAD83.
