Summary

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

  • Geosoft Grid
  • ESRI Geodatabase
  • ASCII Grid

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 Electromagnetics V3 database, using a cell size of 35m.

The following file are provided:

##TELLUS_Electromagnetic (Minc from V3 gdb, cellsize 35m) 3KHz_Acon_FLT 3 kHz Apparent Conductivity generated using the Minimum Curvature interpolation method, from data contained within the 3KHz_Acon_FLT channel of the Electromagnetics V3 database, using a cell size of 35m.

##TELLUS_Electromagnetic (Minc from V3 gdb, cellsize 35m) 3KHz_Acon_FLT_GRD_s A sunshade of the 3 kHz Apparent Conductivity generated using the Minimum Curvature interpolation method, from data contained within the 3KHz_Acon_FLT channel of the Electromagnetics V3 database, using a cell size of 35m Shading parameters (inclination = 45 degrees, declination = 0 degrees).

##TELLUS_Electromagnetic (Minc from V3 gdb, cellsize 35m) 14KHz_Acon_FLT 14 kHz Apparent Conductivity generated using the Minimum Curvature interpolation method, from data contained within the 14KHz_Acon_FLT channel of the Electromagnetics V3 database, using a cell size of 35m.

##TELLUS_Electromagnetic (Minc from V3 gdb, cellsize 35m) 14KHz_Acon_FLT_GRD_s A sunshade of the 14 kHz Apparent Conductivity generated using the Minimum Curvature interpolation method, from data contained within the 14KHz_Acon_FLT channel of the Electromagnetics V3 database, using a cell size of 35m Shading parameters (inclination = 45 degrees, declination = 0 degrees).
