Airborne geophysical survey: Sherbrooke-Lewiston, New Hampshire

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.

航空磁测数据由搭载于航空器的仪器沿飞行测线采集，该仪器可同步记录磁场强度值与位置信息。本数据集包含纬度、经度、海拔高度及磁场强度值。
