Small-format aerial photography (SFAP) is a low-cost solution for bridge-surface imaging and is proposed as a remote bridge-inspection technique to supplement current bridge visual inspection. Providing top-down views, photos taken from airplanes fly

The National Bridge Inspection Standards (NBIS), which were last revised in 2005, require every public bridge to be inspected at least once every two years. Since the 1980's, the United States Department of Transportation (USDOT) has spent millions o
