Dear John, The best I can do is offer names and numbers of people who did ours. The tiger files for our urban parishes were rectified to 9" spatial resolution panchromatic aerials by a contractor: 3001 The Spatial Data Company. Since this is how they make money, I don't know if they will help with advice or not, but worth a phone call (504) 733-3001 Address: 5525 Mounes St. Harahan, LA 70123. Also, the census bureau is using our region as a test area for rectifying all 5 parishes to the 1998 DOQQ CIR aerials. They also have hired a contractor (everyone knows how much fun this isn't.) The census bureau contact is: rfusaro(a)geo.census.gov. Here is a clip from her last message:The status is that the contractors are in the process of extracting the vectors from the imagery. I have no idea when the rectified TIGER/Lines are due in, as the extracted vectors go to a different contractor for TIGER Matching and coordinate replacement. This whole process has been incredibly slow, and quite a learning experience. I will keep you posted as anything new occurs. Randi Fusaro at census may be helpful, since they would like this done for the entire country. That's the best I can for now. If I hear of anything, I'll forward it along.
