Service Description: A grid of the reduction-to-the-pole (RTP) magnetic intensity for the Saint John 1987 survey.This dataset represents the reduction-to-the-pole (RTP) of total magnetic intensity for the Saint John airborne magnetic survey in southern New Brunswick. RTP processing repositions magnetic anomalies directly over their causative sources, improving the clarity of subsurface structures and supporting geological interpretation. The dataset is provided in NB Stereographic Double, NAD83.The RTP grid was created from the Saint John 1987 survey by microlevelling the TMI, converting it to a grid, and applying reduction-to-the-pole processing using magnetic inclination and declination from the IGRF model. The final grid is provided in NB Stereographic Double, NAD83.Data created Sept 2025.
