ABSTRACT:
A method and apparatus for recording the image of an object, for instance the earth's surface, from a flying body, in this case an earth satellite. The flying body flies over the object at an altitude. Herein, the object is scanned in lines by a line scanner. The viewing angle .alpha. of the liner scanner with respect to the direction of flight v is increased during the scanning process, whereby a higher resolution capacity is attained. Preferably several line sensors are used in the line scanner, which are arranged on a carrier, which is displaced during the flight of the flying body relative to a length in the direction of flight v. The displacement occurs by way of a cyclically functioning drive.
