This paper was written to demonstrate that the photogrammetric method is a science capable of providing highway engineers with an integrated and complete system of surveying for obtaining the qualitative information and quantitative data about the ground surface required for the route location preliminary survey, design, location survey, and construction stages of urban highway projects. All except the last two stages can be completed prior to a ground survey party occupying the actual centerline of any particular project. Urban projects are emphasized, because it is on this type of project that maximum utilization of the photogrammetric method can be realized. This is not to say, however, that variations of, or use of portions of, this method cannot be economically applied to all other types of highway projects as is now being done by a substantial number of highway.
