The national firm of Karl Zeiss Jena is now mass-producing the Stereometrograph, a general purpose stereophotogrammetric instrument of first-order accuracy. The instrument is designed for compiling the relief and planimetric detail for topographic maps from 18 x 18-cm or 23 x 23-cm vertical serial photographs with a focal length of 98-215 mm. The stereometrograph automatically registers the coordinates of model points, converts them into a geodetic coordinate system, calculates areas, and determines the corrections for elements of reciprocal orientation in the aerial photographs and for elements of exterior orientation in the stereo-model. The basic specifications of the instrument are listed, and its operation is described in detail using schematic diagrams.
