Airborne geophysical survey: Upper Michigan West, Michigan Survey Part 2 of 2

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.

航空磁测数据由航空器搭载的仪器沿飞行航线采集，该仪器同步记录了磁场强度数值与位置信息。本数据集收录了纬度、经度、海拔高度以及磁场强度数值。
