NADR reflects the total gamma-ray counts from near-surface rocks and soils, providing a measure of overall natural radioactivity useful for geological interpretation. The dataset is provided in NB Stereographic double (NAD83) for consistent province-wide coverage.</SPAN></SPAN></P><P><SPAN STYLE="font-size:16pt"><SPAN>The NADR grid was produced by compiling individual NRCan radiometric survey grids, microlevelling line-to-line variations, and interpolating the results to a seamless 50 m cell-size raster. The final raster was projected to NB Stereographic double (NAD83) and delivered as individual grid</SPAN></SPAN></P><P><SPAN>The dataset is not updated regularly. Updates occur only if new reprocessing, corrections, or additional surveys become available. As of now, the compilation represents the most recent processing as of December 2025.</SPAN></P></DIV></DIV></DIV> |
