Airborne geophysical survey: Albuquerque 1° x 2° Quadrangle

Aeromagnetic and aeroradiometric data were collected along flight lines by
instruments in an aircraft that recorded magnetic-field and radiometric
values and locations. The magnetic data set presents latitude, longitude,
altitude, and magnetic-field values. Geologic symbols or codes are also
included. The geologic symbols were picked from surficial geologic maps.
The radiometric data set presents latitude, longitude, altitude, geologic
symbols or codes, apparent Uranium (Bismuth 214), Thorium (Thallium 208),
and Potassium (K 40), the element ratios, and ancillary information.

本数据集涵盖航空磁测数据与航空放射性测量数据，均由航空器搭载的测量仪器沿预设飞行航线采集，同步记录磁场强度、放射性参数与测点位置信息。
航空磁测数据集包含纬度、经度、海拔高度及磁场强度数据，同时附带地质符号或编码，该类地质符号均取自地表地质图。
航空放射性测量数据集包含纬度、经度、海拔高度、地质符号或编码、视铀量（铋214校正）、钍量（铊208校正）、钾（钾40）含量、元素比值及辅助信息。
