It was derived from NRCan airborne magnetic surveys originally flown at 800–1000 m line spacing. The BigT_TMI_diff values are calculated by converting the total magnetic intensity (TMI) into magnetic field components (X, Y, Z) and computing the vector magnitude difference between TMI and BigT. The dataset is provided in NB Stereographic double (NAD83) for consistent province-wide coverage. </SPAN></SPAN></P><P STYLE="font-size:16ptmargin:0 0 0 0;"><SPAN><SPAN>The dataset was created from existing NRCan TMI survey grids, converted to ER Mapper format, reprojected to NB Stereographic double, and processed to calculate the BigT_TMI difference from the TMI using magnetic field components.</SPAN></SPAN></P><P><SPAN STYLE="font-size:16pt">Data created Sept 2025.</SPAN></P></DIV></DIV>
