FGDL QUALITY ASSURANCE STATUS:

Photos were registered to SPOT Panchromatic (black & white) satellite imagery using
a minimum of 8 points. SPOT Pan has a spatial resolution of 10 meters and meets
1:25,000 National Map Accuracy Standards. Accuracy of SPOT Pan was verified by
collecting Global Positioning System (GPS) points for selected road intersections in
each of the counties. GPS points have a spatial accuracy of plus or minus 1-3
meters.
