North Dakota Aeromagnetic and Gravity Maps and Data: A Web Site for Distribution of Data

By Ronald E. Sweeney and Patricia L. Hill

U.S. Geological Survey Open-File Report 03-249


Version 1.0

A composite North Dakota magnetic anomaly grid of 1000 meter spacing has been created from 13 individual aeromagnetic surveys at a simulated flight altitude of 304.8 meters (1000 feet) above ground. Individual surveys with higher resolution are also included as well as images of these products. Bouguer and isostatic gravity anomaly grids of 1000 meter spacing and corresponding images generated from 28,174 gravity stations are also available on this site.
