GSNI Tellus Regional Airborne Geophysical Survey - Radiometrics

This dataset presents the results of the Tellus Radiometric survey as xyz data. Channels in the dataset are: X: Grid Easting (m) Y: Grid Northing (m) LAT: WGS84 latitude in decimal degrees LONG: WGS84 longitude in decimal degrees FID: numerical sum of Julian day and seconds past previous midnight Flight: Flight number Day: Day number (Julian) Date: Date (YYYYMMDD) Time: Time (HHMMSS.SS) DIR: Flight direction (degrees clockwise) RALT: Radar altitude (m) BALT: Barometric altitude (m) TOUT: External temperature (degrees C) GPS_H: GPS altitude (m) above geoid (WGS84) DTM: Digital Terrain Model (m) D_TOT_CPS: Total Counts (Ur units) meaning sum of all counts from 400 to 3000 keV D_TOT_NGY: Total counts (nGy/h = nanoGray per hour) expressed as air absorbed dose rate D_KAL: Potassium (%K) D_URA: Uranium (ppm, eU) D_THO: Thorium (ppm, eTh)
