EDMAP is a matching-funds grant program with universities that is an interactive and meaningful program for students to gain experience and knowledge in geologic mapping as well as contribute to the national eort -- Federal, State, university -- to geologically map all of the United States. This program is intended to train the next generation of geologic mappers and is one of the three components of the congressionally mandated U.S. Geological Survey National Cooperative Geologic Mapping Program (NCGMP). Geology faculty, skilled in geologic mapping, request EDMAP funding to support upper-level undergraduate and graduate students at their institution in a one-year mentored geologic mapping project that focuses on a specic geographic area. Also, each EDMAP proposal must be closely coordinated with a State Geologist or a USGS geologic mapping project. Every federal dollar awarded is matched with university funds. EDMAP has supported 144 universities and over 850 students from geoscience departments across the Nation.
