Virginia Aeromagnetic Data Index Map

Note: The small unlabeled green areas in the northeastern part of the state are all part of Project No. 350.

The Virginia aeromagnetic compilation map contains data from 23 separate aeromagnetic surveys and digitized maps. This map is an index to the location and flight line spacing of the original surveys. The tabular index below provides a summary of the data sources. References are listed in the bibliography. Selected digital data are available from the National Geophysical Data Center (NGDC), Boulder, Colorado.  Files of digitized analog surveys may be downloaded from the USGS site: http://greenwood.cr.usgs.gov/pub/open-file-reports/ofr-99-0557/html/mag_home.htm. Digital flight line data for most surveys flown since about 1973 are available from the USGS site: http://pubs.usgs.gov/of/2002/ofr-02-361/
