    Description

    Butcher paper, surveyor stakes, lath strips, plastic letter-number codes, paper plates, and drop-panel markers were all useful for marking range ground features, providing strict flightline control, and interpreting resultant aerial photographs. All markers were both highly detectable and resolvable at the largest scale of 1:600. All markers remained visible, yet some became less resolvable, at the smaller scales of 1:2400 and 1:4600.
