description: A grid of BigT (total magnetic field magnitude) for the SWN 2010 survey.This dataset represents BigT, the total magnetic field magnitude, for the SWN airborne magnetic survey in southern New Brunswick. BigT is calculated by converting total magnetic intensity (TMI) to magnetic field components (X, Y, Z) and computing the vector magnitude, providing a clear overview of magnetic anomalies and sources. The dataset is provided in NB Stereographic Double, NAD83.The BigT grid was created from the SWN 2010 survey by microlevelling the TMI (Mag_Miclev), converting it to magnetic field components, and calculating the vector magnitude (√(X² + Y² + Z²)). The final grid is provided in NB Stereographic Double, NAD83.Data created Sept 2025.
