Alaska High Altitude Aerial Photography - AHAP
CIR photos flown by NASA Ames and NASA Johnson, roughly 1" = 1 mi. AHAP photos were acquired between 1978 and 1986. B&W photos are 2" - 1 mi.
This is an index we use to locate AHAP photography. Flight lines are E/W or W/E, every 6' of latitude, for most of the state, but there are also some N/S and some at an angle in SE. The longitude is a range.
