Photogrammetry for highway engineering

Photogrammetry is the science or art of obtaining reliable measurements by means of photography in order to determine, primarily geometric characteristics such as size, form and position of the photographed object. In highway engineering the major aim of photogrammetry is to serve as an aid in terrain mapping. Terrain mapping or topographical surveys produced from aerial photographs are a familiar sight to engineers engaged in the route location and design processes. There are many variances from this form that are invariably called upon to assist the engineer in his task. To make no reference to these facilities would be to do photogrammetry an injustice. However, i would merely acknowledge the fact that technology continues to offer more and engineers should attempt to maintain an awareness of these changes. To further explain the processes involved in producing a topographic map via photogrammetry a brief explanation of the aerial photograph and its properties is warranted.
