The RTP_TDR emphasizes edges of magnetic sources and shallow anomalies, aiding detailed structural and geological interpretation. The dataset is provided in NB Stereographic double (NAD83).The RTP_TDR grid was created from NRCan airborne profile data that were microlevelled and gridded at 50\u202fm, converted to ER Mapper format, reprojected to NB Stereographic double, processed with reduction-to-the-pole, and then the tilt derivative of the RTP was calculated.Data created Sept 2025.", "name": "Geophysics_Aeromagnetic_Compiled/NB_Highres_RTP_TDR", "description": "A 50\u202fm grid of the tilt derivative of the reduction-to-the-pole (RTP) magnetic intensity for New Brunswick.This dataset represents the tilt derivative (TDR) of the reduction-to-the-pole (RTP) magnetic intensity for New Brunswick at 50\u202fm resolution, derived from high-resolution airborne magnetic surveys flown at 200\u2013300\u202fm line spacing.
