VOXI- gravity data inversion

I'm processing gravity data. i'd like to invert the grid by using voxi. Which grid must be used (free-air, bouguer, complete bouguer or anomaly?)

Since, for example, Bouguer Anomaly takes into account for free-air and slab correction, what must I use during the creation of the voxi (In the SURFACE ELEVATION (constant or dem)) and during the ADD DATA in the SENSOR ELEVATION menu?


  • Hi Filippo, you can use either the Free Air or Bouguer Anomaly as input. Note that VOXI outputs a voxel of density relative to the background density. Therefore, if FAA is used density values are relative to 0 g/cc, if BA is used density values are relative to the terrain correction density.
