Airborne geophysical survey: West-central Wisconsin, Wisconsin

Aeromagnetic data were collected along flight lines by instruments in an
aircraft that recorded magnetic-field values and locations. This dataset
presents latitude, longitude, altitude, and magnetic-field values.

航空磁测数据（Aeromagnetic data）由搭载于飞行器的仪器沿飞行航线采集，同步记录磁场强度与位置信息。本次公开数据集包含纬度、经度、海拔高度以及磁场强度四项参数。
