Aerial Photographs

Aerial Photographs are usually exposed at scales from 1:10,000 to 1:50,000, varying slightly due to such factors as shrinkage or expansion of the paper caused by atmospheric conditions, uncertainty in the reported flight altitude, and ground relief. The ground area varies with the scale as follows:

5.2 sq. km (2.0 sq. mi.)

2.29 km (1.42 mi.)

1:12,000

2.74 km (1.70 mi.)

1:20,000

20.9 sq. km (8.1 sq. mi.)

4.57 km (2.84 mi.)

1:30,000

47.1 sq. km (18.1 sq. mi.)

6.86 km (4.26 mi.)

1:40,000

83.5 sq. km (32.3 sq. mi.)

9.14 km (5.68 mi.)

1:50,000

130.6 sq. km (50.4 sq. mi.)

11.43 km (7.10 mi.)

Photographs are indexed on 1:250,000-scale base maps, with a dot indicating the center position of each individual exposure. The first and last exposure of a line, and several in between, are labeled. Paper copies of these indexes are available for $14 each. Aerial photographs covering approximately 920 of the largest airports in the United States and its possessions are also available and are priced according to the schedules below. These are normally black-and-white photographs exposed at a contact scale of approximately 1:30,000.

Black-and-White Photographs: Prices of contact prints, film positives or negatives, and enlargements are the same for black-and-white and black-and-white infrared photographs. They are printed on medium-weight glossy paper, unless medium-weight matte is specified.

Color Photographs: Before 1987, most NOAA color aerial photographs were exposed on color positive film. Since then, most have been exposed on color negative film. Prices of contact prints, film positives or negatives, and enlargements are the same for natural color and false-color infrared photographs. All color photographs are printed on glossy-finish material, unless semi-matte is specified.
