The mapping of the Earth’s subsurface is a scientific and technical challenge. The creation of such maps can result in a greater understanding of our capabilities and limitations with regard to agriculture, construction, transportation, environmental assessment, and resource management. Additionally, water, nutrients, pesticides, and herbicides must flow through or be contained by the soil environment. Subtle changes in soil properties can have large impacts on land usability, solute transport calculations, soil fertility, carbon sequestration, bioremediation, and vegetative health. Intensive land use applications and management practices require more detailed subsurface information than is currently available in most instances. Information regarding the depth, thickness, and properties of subsurface strata are currently obtained through soil core sampling, well logs, or the excavation of pits to enable detailed analysis of the characteristics of the ground on which we all live.
