Airborne geophysical survey: Tobacco Roots, Montana

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，仪器同步记录了磁场强度值与位置坐标。本数据集包含纬度、经度、海拔高度及磁场强度值四类核心数据。
