This dataset presents the results of the Tellus Magnetic data as xyz data. Channels in the dataset are: X: Grid Easting Y: Grid northing LAT: WGS84 latitude in decimal degrees LONG: WGS84 longitude in decimal degrees FID: numerical sum of Julian day and seconds past previous midnight Area: Tellus survey area Flight: Flight number DATE: Date (YYYYMMDD) Day: Day number (Julian) Time: Time (HHMMSS.SS) DIR: Flight direction (degrees clockwise) RALT: Radar altitude (m) GPS_H: GPS altitude (m) above geoid (WGS84) DTM: Digital Terrain Model (m) MAG_MID: Total magnetic Intensity for aircraft mid-point (nT) BASE: Magnetic basestation correction (nT) GRAD_PERP: Gradient perpendicular to aircraft (nT/m) MAG_ML: Equivilent to MAG_MID microlevelled (nT) MAG_IGRF: IGRF field (nT) MAG_RES: Magnetic anomaly (IGRF corrected MAG_ML) (nT)
