| description:
|
A 200 m grid of the reduction-to-the-pole (RTP) magnetic intensity for New Brunswick.This dataset represents the reduction-to-the-pole (RTP) of total 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. RTP processing repositions magnetic anomalies over their causative sources, providing a clearer interpretation of subsurface geology. The dataset is provided in NB Stereographic double (NAD83) for consistent province-wide coverage. The RTP grid was produced by converting existing NRCan TMI survey grids to ER Mapper format, reprojecting to NB Stereographic double, and applying reduction-to-the-pole processing to the TMI values.Data created Sept 2025. |
