| description:
|
A 200 m grid of the regional trend of total magnetic intensity (TMI) for New Brunswick.This dataset represents the regional trend of total magnetic intensity (TMI) 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 regional trend highlights broad, long-wavelength magnetic variations and provides a baseline for calculating residual magnetic intensity or other derivative products. The dataset is provided in NB Stereographic double (NAD83) for consistent province-wide coverage.The TMI regional trend grid was produced by converting existing NRCan TMI survey grids to ER Mapper format, reprojecting to NB Stereographic double, and fitting a second-order trend surface to the TMI data.Data created Sept 2025. |
