A 200 m grid of the horizontal gradient of the reduction-to-the-pole (RTP) magnetic intensity for New Brunswick.
A 200 m grid of the horizontal gradient of the reduction-to-the-pole (RTP) magnetic intensity for New Brunswick.This dataset represents the horizontal gradient of the 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 RTP_Hgrad highlights the edges of magnetic sources, helping to delineate geological contacts and structures. The dataset is provided in NB Stereographic double (NAD83) for consistent province-wide coverage.The RTP_Hgrad 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 then calculating the horizontal gradient of the RTP grid.Data created Sept 2025.
