    • Phototriangulation with Analyatical Plotters 

      Armin Gruen (American Society of Civil Engineers, 1983)
      A phototriangulation technique with analytical plotters which uses natural tie points only is described. Artificial image point marking or ground point targetting is not necessary any more. This leads to a highly economic ...
    • Non‐Center Line Layout 

      Frank Pearson (American Society of Civil Engineers, 1983)
      A line identifying some part of construction, e.g. a road centerline, is a series of line segments joining points of intersection, with intervening curves. The coordinates of each point of intersection, and the equation ...
    • Area Computation Using Salient Boundary Points 

      Fouad A. Ahmed (American Society of Civil Engineers, 1983)
      An approach is developed to determine the area bounded by irregular curves. Points of maximum and minimum deviations from the datum together with points of curvature inflections are determined in the field and offsets to ...
