Missouri Geologic Map Index

What are geologic maps and how are they used?

American Institute of Professional Geologists -- Mapping for the Future

The U.S. Geological Survey's National Cooperative Geologic Mapping Program currently funds 127 projects from 45 states. These projects include both bedrock and surficial geologic mapping, and digital compilation of geologic maps. Missouri competes annually, for federal matching funds for geologic mapping. The Missouri Geological Survey has participated in the program since 1993. See this PDF data sheet for a list of maps and related information.

The primary objective of the STATEMAP component of the NCGMP is to establish the geologic framework of areas that are vital to the welfare of individual states. Each State Geologist determines the state's mapping priorities in consultation with a State Mapping Advisory Committee. These priorities are based on state requirements for geologic map information in areas of multiple-issue need or compelling single-issue need and in areas where mapping is required to solve critical Earth science problems.

In recent years, STATEMAP efforts have focused primarily on geologic maps that address water, aggregate, and mineral resources; and landslide and earthquake hazards. As shown in the chart, these maps are used less widely to address issues such as flooding, radon, and mine subsidence hazards; and ecosystem and wetland issues.

Each STATEMAP project focuses on a specific area or issue. Although the individual projects last for only one year, they frequently build upon the results of previous years' mapping activities.
