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.
