Airborne geophysical survey: Southeast 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.

航空磁力数据系由搭载于航空器的探测仪器沿飞行航线采集所得，该仪器同步记录磁场强度数值与位置信息。本数据集涵盖纬度、经度、海拔高度及磁场强度值。
