Title: Ecological surveys from space
Description: "A small sampling and condensation of numerous scientific and technical studies of new images and concepts of the Earth that men have acquired by venturing into space. It is intended mainly to call the attention of more specialists, such as geographers, agricultural engineers, foresters, geologists, hydrologists, oceanographers, and cartographers, to the potentialities of ecological surveys from orbiting satellites ... The photographs reproduced here were taken from aircraft and the Gemini and Apollo vehicles."--Page ii.
