| Airborne Magnetic Trackline and Survey Data (Vector and Scaler 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.
