U.S. Geological Survey Information Sources

As the nation's largest water, earth and
biological science and civilian mapping
agency, the U.S. Geological Survey
(USGS) works in cooperation with more
than 2000 organizations across
the country to provide reliable, impartial,
scientific information to resource
managers, planners, and other customers.
This information is gathered in every
state by USGS scientists to minimize the
loss of life and property from natural
disasters, to contribute to the
conservation and the sound economic
and physical development of the nation's
natural resources, and to enhance the
quality of life by monitoring water,
biological, energy and mineral resources.
