Voxel to SEG-Y

Use the Voxel > Conversions > Voxel to SEG-Y menu option (geogxnet.dll(Geosoft.GX.ConvertVoxelToSegY;Run)*), to export a Geosoft Voxel to a 3D SEG-Y file.

Export Voxel to SEG-Y dialog options

Input voxel

Select the Geosoft Voxel file to be exported.

Script Parameter: CONVVOXTOSGY.INPUT_VOXEL

Output SEG-Y name

Specify the name of the 3D SEG-Y file to be created.

Script Parameter: CONVVOXTOSGY.OUTPUT_SEGY

Vertical sample interval

Specify the constant vertical sample interval to be used.

Script Parameter: CONVVOXTOSGY.SAMPLE_INTERVAL

Application Notes

  • The voxel to be exported must be a numeric Geosoft voxel.

  • The text header is exported in ASCII format.

  • Only voxels with constant cell sizes in X and Y can be exported.

  • Irregular cell sizes in Z will be re-sampled to a user-specified constant sample interval.

  • All voxel values will be converted to 4-byte IEEE floating point values.

  • Dummy values in the voxel will be converted to zero in the SEG-Y file.

  • If all cells in the voxel at an X, Y location (a vertical trace) are dummy, the entire zeroed trace will be marked as "dead" in the SEG-Y file.

  • Rotation about the Z-axis is supported, but rotations about the X- or Y-axes are not.

*The GX.NET tools are embedded in the geogxnet.dll file located in the "...\Geosoft\Desktop Applications \bin" folder. If running this GX interactively, bypassing the menu, first change the folder to point to the "bin" directory, then supply the GX.NET tool in the specified format. See the topic Run GX for more details on running a GX.NET interactively.
