trimetrogon method
Quick Summary
The trimetrogon method is a system used in aerial mapping that employs a single assembly with three cameras. These cameras simultaneously capture one vertical and two oblique (left and right) aerial photographs. This process allows for the mapping of an area by taking these shots at regular intervals along the line of flight. This technique was notably used during World War II to photograph large areas of the world, providing reconnaissance maps that served as bases for aeronautical charts. The trimetrogon process typically photographs terrain from horizon to horizon across the flight path from an altitude of approximately 20,000 feet, with detail visible for several miles on each side.12
