Service Description: A grid of the first vertical derivative (ddz) of the reduction-to-the-pole (RTP) magnetic intensity for the Marrtown 2004 survey.This dataset represents the first vertical derivative (ddz) of the RTP magnetic intensity for the Marrtown airborne magnetic survey in New Brunswick. The RTP_ddz emphasizes near-surface magnetic sources and sharpens anomaly edges, supporting detailed geological and structural interpretation. The dataset is provided in NB Stereographic Double, NAD83.The RTP_ddz grid was created from the Marrtown 2004 survey by microlevelling the TMI, applying reduction-to-the-pole processing, and then calculating the first vertical derivative of the RTP grid. The final grid is provided in NB Stereographic Double, NAD83.Data created Sept 2025.
