South Dakota Aeromagnetic Maps

South Dakota Aeromagnetic Anomaly Maps - Higher-Resolution

These individual aeromagnetic residual anomaly grids/maps were generated using with the most representative grid interval for the flight-line spacing of the survey and maintained at the original flight altitude of the individual survey. They were then regridded to the 1000 meter interval and continued to the 1000 feet flight altitude used in the state compilation.

Select an aeromagnetic map from the list below. All maps are displayed with an illumination from the Northeast. The images were generated with a resolution to fit the screen and not with regard to original grid interval. Grids for these maps can be acquired from the data directory. For a full description of survey specifications see page Get Survey Info.
