The Core Science Metadata Clearinghouse is an initiative by the USGS Core Science Analytics and Synthesis (CSAS) program to locate, evaluate, and access earth science data and information from cooperating data partners and information sources. The Clearinghouse also provides access to software tools to use in analyzing, integrating, and applying data.

The Core Science Metadata Clearinghouse contains standardized metadata descriptions of earth science data sets and information products. Metadata descriptions follow the Federal Geographic Data Committee's (FGDC's) Content Standards for Digital Geospatial Metadata. The Clearinghouse is also a participating node on the FGDC's National Spatial Data Clearinghouse (NSDI) and the Geo.Data.gov. The Core Science Metadata Clearinghouse is comprised of contributions from many different organizations to help scientists find a broad spectrum of data. Metadata in the Clearinghouse describes both geospatial and data that is not as explicitly geospatial, such as results of laboratory research. For instructions about how to submit your individual metadata records to the Clearinghouse, go to Submit Metadata.

Join Us! Organizations interested in establishing a unique metadata presence can become a Clearinghouse data provider. The Core Science Metadata Clearinghouse providers make their metadata records available through a weekly harvesting process from CSAS.
