Abstract: Modeling the stratigraphy beneath a site and assigning soil and rock properties are important steps in geotechnical engineering. Geotechnical engineers often need to model ground conditions over extensive terrain. Although a vast amount of information is available in the form of electronic quad maps, satellite images, and elevation models, these sources by themselves do not provide the level of detail needed to accurately depict site conditions. Surveyors provide a wealth of additional data useful to the civil aspects of capital projects, such as electronic data in the form of ground elevations, ground features, terrain configuration, and more. These data, when further processed, give engineers a graphical representation of the areal extent, surficial features, and topography at a site.
