ABSTRACT
It is very difficult to conceive of the planning without the aid of photogrammetry of any civil engineering projects covering considerable areas of terrain — those concerned with the construction of roads, railways, dams, reservoirs, airfields, pipelines, large housing developments and opencast mining. Certainly there is no other method of survey which will generate the required data about the terrain surface in the form of accurate plans, maps, photomaps, elevation models, profiles and contours in a timely and economic manner as is required for the planning of all large civil engineering projects nowadays.
