description: A 200 m grid of residual reduction-to-the-pole (RTP) magnetic intensity for New Brunswick.This dataset represents the residual reduction-to-the-pole (RTP) magnetic intensity for the province of New Brunswick at 200 m resolution. It was derived from NRCan airborne magnetic surveys originally flown at 800–1000 m line spacing. The residual RTP is calculated by removing a second-order regional trend from the RTP, emphasizing local magnetic anomalies for geological interpretation. The dataset is provided in NB Stereographic double (NAD83) for consistent province-wide coverage.The residual RTP grid was produced by converting existing NRCan TMI survey grids to ER Mapper format, reprojecting to NB Stereographic double, applying reduction-to-the-pole processing, and removing a second-order trend from the RTP grid.Data created Sept 2025.
