Airborne Magnetic Trackline and Survey Data (Vector and Scalar Observations)
The National Geophysical Data Center (NGDC) receive airborne magnetic survey data from US and non-US agencies. In an effort to provide a central library for digital aeromagnetic data in the public domain, the National Geophysical Data Center (NGDC) is continuing to assimilate new digital data from aeromagnetic surveys in the United States. Major contributors to this important data base include the U.S. Geological Survey, U.S. Naval Oceanographic Office, U.S. Naval Research Laboratory, Woods Hole Oceanographic Institution, the University of Texas, and the Natural Resources Canada (NRCAN). The details of these surveys are contained in an automated inventory system Geophysical Data System (GEODAS). The philosophy of exchange of data from the NGDC archive for new contributions has stimulated many organizations to transfer their data holdings to the Data Center.
