How would you like to acquire aerial photographs of, say, your home town as it appeared in a recent
year, as well as during the 1980s, the 1970s, the 1960s, and so forth? Aerial photographs are great tools
for analyzing the geography of an area and how it has changed over time. And when it comes to air
photos of the U.S., nobody beats APFO. This branch of the Department of Agriculture serves as the
storehouse for aerial photographs of the United States produced under government backing from as far
back as the 1930s. The inventory consists of literally millions of air photos, all of which are available
to the public. Prices start at $6 for 9” x 9” black-and-white prints that were standard fare through the
mid-1970s, and go higher for infrared prints from more recent aerial surveys. The costs are a fraction
of what you would pay a local aerial survey firm for the very same thing, the difference being that
APFO is a non-profit government agency.
