Index Map of Aeromagnetic Surveys

Index Map of South Carolina Aeromagnetic Surveys

 

The South Carolina composite aeromagnetic map contains data from 11 aeromagnetic surveys as shown in the above index map.  The survey numbers are keyed to the table below.  

Flight line data for the digitally recorded surveys (data type=digital) are available from a USGS web site: http://pubs.usgs.gov/of/2002/ofr-02-361/ (U.S. Geological Survey and National Geophysical Data Center, 2002)

Analog survey data  (data type=analog) are available from USGS web site: http://pubs.usgs.gov/of/1999/ofr-99-0557/html/mag_home.htm (U.S. Geological Survey, 1999)

Description of Table headings:

Survey No.: Internal USGS identification number
Data Type: Survey data were recorded in flight as analog or digital
Survey Name: Internal project name (not always the name used in publication title)
Flown By: Company or government agency who flew the original survey
Flight Spacing and Flight Direction: Primary flight-line spacing and primary flight-line direction
Flight Altitude: Primary flight altitude ; B = barometric elevation, AG = above ground draped over topography
Flight-Line Miles: Approximate total of line miles flown for this survey
Field, Datum: Indicates if a regional field was removed and, if it could be determined, the base value removed. Total field = no regional was removed. Arb. (arbitrary) datum = the base value removed was not stated on the map or in survey reports.
References: Brief publication reference. USGS publications are listed as: Open-File reports = OFxx-yyyy where xx is the publication year, Bulletins and Professional Papers = B-yyyy or P-yyyy, Geophysical Maps = GP-yyyy, Miscellaneous Field Studies Maps = MF-yyyy.
