North-Western Nevada [A1029]

Most of Nevada is covered by proprietary, nonexclusive aeromagnetic data flown between 1978 and 1988.

These aeromagnetic data are superior to those available in the public domain for several reasons. The surveys were flown to uniform specifications; the profile data are available and are in digital form; the surveys were flown on a square grid, not just east-west as were most of those in the public domain; processing of the data is state-of-the-art.
