A 200 m grid of the total gradient (analytic signal) of the total magnetic intensity (TMI) for New Brunswick.
A 200 m grid of the total gradient (analytic signal) of the total magnetic intensity (TMI) for New Brunswick.This dataset represents the analytic signal (total gradient) of the 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 TMI_AS highlights the edges and positions of magnetic sources, independent of the magnetization direction, providing clearer identification of geological structures. The dataset is provided in NB Stereographic double (NAD83) for consistent province-wide coverage. The TMI_AS grid was produced by converting existing NRCan TMI survey grids to ER Mapper format, reprojecting to NB Stereographic double, and calculating the total gradient (analytic signal) from the TMI values.Data created Sept 2025.
