Airborne geophysical survey: Glens Falls 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.本数据集包含沿飞行航线采集的航空磁测与航空放射性测量数据，相关数据由航空器搭载的测量仪器采集，同步记录磁场强度、放射性测量值及采样位置信息。其中磁测数据集包含纬度、经度、海拔高度及磁场强度数值，同时附带地质符号或编码信息，此类地质符号源自地表地质图件。放射性测量数据集则包含纬度、经度、海拔高度、地质符号或编码、表观铀（铋214）、钍（铊208）、钾（钾40）含量、元素比值及辅助信息。
