Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted.  For more information, please see www.doi.gov/shutdown

Peter N Schweitzer, Ph. D.

Peter Schweitzer works on scientific information management at the U.S. Geological Survey in Reston Virginia.  With a formal background in geology and oceanography and practical experience in software development, he serves as a bridge between the scientific research and information technology communities.


Currently my work focuses on providing usable scientific data to the public through the internet.  Perhaps best known for producing widely-used software that parses and validates geospatial metadata, I have more recently led a small team to develop controlled vocabularies and used cataloging software to design a topical index of scientific information on the web.

Web sites through which my work is visible:

Mineral Resources on-line spatial data

Mineral Resources data catalog

Formal metadata information and software

USGS Geoscience Data Catalog
