The production of foundation data simultaneously with topographic control for highway location and design is created by researching, processing, and presenting the geologic and soils information along a proposed highway location at the same time photogrammetic maps are being plotted. The foundation data are researched from existing field surveys on geology, soils, and hydrology. Photo interpretation is used to detect foundation problems such as landslides, collapse of mine voids, peat bogs, and wet zones. A field check verifies the remote-sensing and foundation data and provides additional first-hand information in critical areas. A written geologic evaluation of the proposed location, with accompanying maps, covers the foundation and slope problems by explaining the geology, soils, and hydrologic controls in the terrain. The cost of this program ranges from 50 to 100 man-hours per mile of proposed highway.
