Quadricamera system.  c1970  aAn aircraft mounting plate for a multiple assembly of 70-mm. cameras was designed and  fabricated by the University of Minnesota School of Forestry with the assistance of Mark Hurd Aerial Surveys, Inc. The basic idea and inspiration for the plate assemblagy was  provided by the CRREL four-camera system. The assemblagy permits up to four simulta- neous exposure which can be stereoscopically viewed and compared at the same time in the uncut film strips. Development, calibration and operation of the system is discussed.  aaerial photography  aAerofotogrametria  aQudricamera system1 aLATHAM, R. P.1 aMEYER, M.
