An easy to use, inexpensive, and rapid system for determination of tilt in an aerial photograph has been developed at the Defense Mapping Agency Aerospace Center. Image measurements are made with a calibrated template and tube magnifier. Geodetic control points are then scaled from a large scale map source. Tilt determination is then accomplished using Church's resection on a programmable calculator, and allows for computation of surface feature lengths, widths, and heights from a single image.
