Note générale :	Imagery expected from the Earth Resources Technology Satellite (ERTS) is simulated by reduction of conventional black and white aerial photography (scale1/20,000) to the small scales (e.g., 1/2,560,000) that would result from photographing large areas of the ground at satellite altitude. Small sections of the reduced negatives are then enlarged for land use interpretation tests. It is concluded that the classification system now used by Economic Research Service, USA, in this inventory of major land uses would be compatible with satellite photography. Data for the following categories cannot be obtained from satellite photography: ownership/ end-use for specific crops/ same transitional vegetation and multiple-use areas.
