Description of Table Columns:

No.: Internal USGS project identification number
Data Type: Data collected as: A=Analog, D=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 Dir.: Primary flight-line spacing and primary flight-line direction
Flight Altitude: Flight altitude in feet; B = barometric elevation, AG = above ground draped over topography
LineMi.: 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. Arbitrary datum = the base value removed was not stated on the map.
Publication: Brief publication reference**. USGS paper contour map publications are for analog surveys. Geophysical Investigations Maps = GP-yyyy,  Open-file Maps = yy-zzz, Miscellaneous Field Investigations= MF-zzz, refers to all or part of the original project area.

* Files of most digitized analog contour maps may be downloaded from the USGS site:  http://pubs.usgs.gov/of/1999/ofr-99-0557/html/mag_home.htm   (U.S. Geological Survey, 1999)
