Digital Aeromagnetic Datasets for the Conterminous United States and Hawaii

Coordinate system: 4269 - "NAD83"

Abstract:

About This DVDAfter pioneering the first airborne magnetic survey in 1945, the U.S. Geological Survey (USGS) has collected piecemeal aeromagnetic data for most of the U.S., including offshore areas on both coasts. The U.S. Geological Survey's digital and analog archives comprise more than 1,000 surveys, covering approximately 8,000,000 line-km of data, flown at various flight heights and line spacings. The purpose of this report is to compile and standardize original aeromagnetic survey data (approximately 5,800,00 line-km) and make them available to the public.This DVD contains currently available digital magnetic files for the conterminous U.S. and Hawaii from the USGS archives. Updates and corrections to files included here can be found on the online release of the datasets (http://pubs.usgs.gov/of/2002/ofr-02-361)This CD is a companion to the North American Magnetic Anomaly Map.
