Description

• X: outputs the X-coordinate

• Y: outputs the Y-coordinate

• Z: outputs the depth according to the survey setup (e.g. miliseconds, meters or feet)

• Inline nr: outputs the inline number

• Crossline nr: outputs the crossline number

• Sample nr: outputs the sample number starting from 0 ms or the top of the survey when the survey has a negative start time. The first sample has sample number 1. If the survey has 4 ms sampling and starts at 0 ms, at 400 ms the sample number is 101. If the survey has 4 ms sampling and starts at 2500 ms, the first sample has sample number 626. If the survey has 2 ms sampling and starts at -200, the sample number at 0 ms is 101.

• Inline index: outputs the number of inlines from the edge of the survey starting at 1 (e.g. If you have an inline range of 2000 to 3000, the inline index will range from 1 to 1001)

• Crossline index: outputs the number of crosslines from the edge of the survey starting at 1 (e.g. If you have a crossline range of 2000 to 3000, the crossline index will range from 1 to 1001)

• Z index: outputs the sample number from the top of the survey starting at 1. (Note: this attribute is identical to sample number if the survey has a negative starting time or starts at 0.)
