Description of Table

No.: Internal USGS identification number
Name: Internal project name (not always the name used in publication title)
Flown By: Company or government agency who flew the original survey
Spacing and Dir.: Primary flight-line spacing and primary flight-line direction
Altitude: Primary flight altitude in feet; B = barometric elevation, AG = above ground draped over topography
LnMi.: Approximate total of line miles flown for this survey
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.
Publication: Brief publication reference*. USGS publications are listed as: Open-File reports = xx-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Maps = GP-yyyy, Miscellaneous Field Studies Maps = MF-yyyy, Miscellaneous Investigations Maps = I-yyyy, Unpub = unpublished data, refers to all or part of the original project area.
