This process converts XY coordinate and derived trace headers between two Coordinate Reference.

Headers Used

  • SX / SY - Source location
  • GX / GY - Receiver location
  • CDPX / CDPY - CDP location (which may or may not be at the bin centre, depending on your input data)

Headers Set

  • SX / SY - Source location - if available, and after transformation from the selected CRS
  • GX / GY - Receiver location - if available, and after transformation from the selected CRS
  • CDPX / CDPY - CDP location - will be either recalculated from the transformed source/receiver location if both are available, or transformed from the input volume's cdpx/cdpy (if available). Systems.
