1 Project 0213 is incomplete. Only the eastern half was digitized.
2 Projects 0214, 0256, 0384B, and 0572 are incomplete. Some of the missing parts have been superceded by newer digital data.
3 All of Project 0686 and part of Project 0638 are fully merged with Project 642. The remaining northern part of Project 0638 is missing.
4 Project 0640 is incomplete. Data from east of -72° is missing.
5 Projects 0706A and 0706B are fully merged with 0688.
6 Digital data sets exist for NH02.  NH01 and MA01 have been digitized.

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)
