A survey of earth resources on Apollo 9 photography
The types of photography obtained on the Apollo 9 mission and on concurrent flights made by supporting aircraft are described. The need for earth resource surveys and the value of aircraft and spacecraft as the platforms from which to make such surveys are considered along with the rational for using multiband photography and the means by which such photography can be enhanced. Aerial and space photographs are presented and analyzed. The feasibility of conducting earth resource surveys by means of space photography is discussed and results are summarized.
