The RTP_TDR emphasizes edges of magnetic sources and shallow anomalies, aiding detailed geological and structural interpretation. The dataset is provided in NB Stereographic double (NAD83).The RTP_TDR grid was created from the Columbia 2000 survey by microlevelling the TMI (Mag_miclev), applying reduction-to-the-pole processing, and then calculating the tilt derivative of the RTP grid. The final grid is provided in NB Stereographic double (NAD83).Data created Sept 2025.", "name": "Geophysics_Aeromagnetic_Individual_Surveys/Colombia_RTP_TDR", "description": "A grid of the tilt derivative of the reduction-to-the-pole (RTP) magnetic intensity for the Columbia 2000 survey.This dataset represents the tilt derivative (TDR) of the RTP magnetic intensity for the Columbia 2000 airborne survey in New Brunswick.
