GSNI Tellus Regional Airborne Geophysical Survey - Radiometric Grids

Data were processed using Geosoft Oasis Montaj and supplied in three formats.

  • Geosoft Grid
  • ESRI Geodatabase
  • ASCII Grid

Please note that the presence of ‘Minc from V3 gdb, cellsize 35m’ in the grid filename indicates that the grid was generated using the Minimum Curvature interpolation method, from data contained within the Radiometrics V3 database, using a cell size of 35m.
