Airborne geophysical survey: Central Wisconsin '97, 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.航空磁测数据由航空器搭载的测量仪器沿飞行航线采集，同步记录磁场强度与位置信息。该数据集包含纬度、经度、海拔高度及磁场强度四项数据。
