STATEMAP receives funds through an annual competitive grant process. Every Federal dollar awarded to a State Geological Survey is matched by a State dollar.
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.
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. Employees of the State Geological Surveys conduct the geologic mapping and frequently
work closely with EDMAP students and their professors, as well as with FEDMAP geologists who may be mapping within the State.
STATEMAP Coordinators and Mappers Forum
On a quarterly basis, the NCGMP hosts a Forum for all STATEMAP coordinators and mappers across the nation. The intent is to provide an opportunity for open discussion, collaboration, and idea-sharing among the states. Our latest forum slides, focused primarily on Cross Sections, can be found here.
State Mapping (STATEMAP) Projects

The NCGMP is currently funding 127 projects from 45 states. These projects include both bedrock and surficial geologic
mapping, and digital compilation of geologic maps.
In recent years, STATEMAP efforts have focused primarily on geologic maps that address water, aggregate, and mineral
resources; and landslide and earthquake hazards. These maps are used less widely to address issues
such as flooding, radon, and mine subsidence hazards; and ecosystem and wetland issues.
State Mapping (STATEMAP) Products
Each year, State Geological Surveys conduct geologic mapping with the help of both NCGMP funds (STATEMAP and

The New Mapping section of the National Geologic Map Database (NGMDB) contains information about geologic maps currently being produced for STATEMAP, as well as for FEDMAP and EDMAP.
The main Geoscience Map Catalog of the NGMDB is continuously updated to include information about published STATEMAP geologic maps and how to obtain them.
