Hiroshima Atomic Bomb had been formulated on mosaic aerial photographies.

   In April 1945, a satellite image of Hiroshima City had been formulated by combining a number of aerial photographs like a mosaic for a strategy plan to drop the Atomic Bomb. Hiroshima City had been made one of target plans during 3 months before the atomic bomb experiment was successful on July 16. The target standard for the Little Boy to be dropped and exploded, where was Aioi Bridge in the center of Hiroshima City, was designated as No. 90.30 on the Map. It had drawn a concentric circles within a radius of 70,00 feet (2.13 Km) from the center of Aioi Bridge (east-west scale: 063, north-south scale: 096). Aerial drawings had been confidential documents for pilots of Enola Gay B-29, bombers and patrols.
