Wisconsin High-Resolution Aeromagnetic Anomaly Maps 

The high-resolution aeromagnetic residual anomaly maps below,  were generated using a grid interval appropriate for the flight-line spacing of the survey and maintained at the original flight altitude.  For the state compilation, the grids were regridded to 250 meter interval and continued to 1000 feet flight altitude.

Select an aeromagnetic map from the list below. 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 page. For a full description of survey specifications see survey info page.

Oconomowoc (WI-10) survey gridded at 50 m.

Fond du Lac (A) (WI-11A) survey gridded at 50 m.

Fond du Lac (B) (WI-11B) survey gridded at 50 m.
