Geologic maps provide information for making real-world decisions. They are used in a variety of applications including industrial and commercial development siting; locating dams, bridges and waste disposal facilities; identifying water availability; and in land use planning, natural hazard evaluations and economic assessments of mineral and energy resources. Bedrock maps identify the rock units at ground surface. Surficial material maps characterize the type of sediment, weathered rock or transported, unconsolidated material lying on top of the rock units.
