Seismic Volumes

Right-click commands for Seismic Volumes in the Data Tree. The group holds SEG-Y-backed seismic volumes and synthetic (forward-modelled) seismic sections.

Source resources: IDR_DT_DEFAULTGROUP, IDR_DT_DEFAULTITEM (+ seismic-only items appended in code).

Group Context Menu​

Right-click the Seismic Volumes group node.

Actions​

  • New — Create a new (empty) entry (ID_GROUPPOPUP_NEW)
  • Group / Ungroup — Organise items into sub-groups (ID_PROJEXP_GROUP / ID_PROJEXP_UNGROUP)
  • Spreadsheet — Spreadsheet view of the group (ID_DEFAULTGROUP_SPREADSHEET)
  • Import — Import SEG-Y files (.sgy / .segy, multi-select). Each file opens the import preview dialog — textual header, auto-detected byte layout, editable fields — before the background scan starts (ID_GROUPPOPUP_IMPORT)
  • Export — Export (ID_GROUPPOPUP_EXPORT)

Item Context Menu​

Right-click an individual seismic volume in the Data Tree.

Actions​

  • Navigate To — Fly the 3D view to the volume (ID_POPUP_ITEM_GOTO)
  • Group / Ungroup — Organise into sub-groups (ID_PROJEXP_GROUP / ID_PROJEXP_UNGROUP)
  • Position — Copy / paste the object position (ID_DEFAULTITEM_COPYPOSITION / ID_DEFAULTITEM_PASTEPOSITION)
  • Coordinate Conversion — Convert between coordinate systems (ID_CONVERTCOORDINATES_CRSTOCRS)
  • Copy URI — Copy the object's project URI (ID_DEFAULTITEM_COPYURI)
  • Export — Export (ID_PROJEXP_EXPORT)
  • Delete — Remove the volume from the project (the SEG-Y file on disk is untouched) (ID_POPUP_ITEM_DELETE)

Seismic-only actions​

These appear only on SEG-Y volumes (synthetic sections get the default items above):

  • Pick Horizon in 3D View — Arms the horizon digitiser: clicks in the 3D view ray-pick the volume's active sections with snap-to-peak, and Enter / double-click commits the points as a standard polyline. See Horizon picking (ID_SEISMIC_PICK_HORIZON)
  • SEG-Y Header & Field Map… — Reopens the import preview for the bound file: the textual header C-cards, the detection summary, and the volume's current trace-header byte layout. Pressing OK with edited values applies the new field map and rescans (ID_SEISMIC_VIEW_HEADER)
  • Compute Attribute ▸ — Flyout that derives a new attribute volume from the cube. See Computing attributes.
    • Per-trace (computed on the fly): Envelope (ID_SEISMIC_ATTR_ENVELOPE), RMS Amplitude (ID_SEISMIC_ATTR_RMS), Instantaneous Phase (ID_SEISMIC_ATTR_INSTPHASE), Instantaneous Frequency (ID_SEISMIC_ATTR_INSTFREQ), Sweetness (ID_SEISMIC_ATTR_SWEETNESS), Relative Acoustic Impedance (ID_SEISMIC_ATTR_RELIMPEDANCE)
    • Structural Dip + Azimuth… (ID_SEISMIC_ATTR_DIPAZIMUTH), Coherence (Semblance)… (ID_SEISMIC_ATTR_COHERENCE), Curvature (K+, K-, mean, Gauss)… (ID_SEISMIC_ATTR_CURVATURE) — volumetric attributes that materialise new SEG-Y files (need a 3-D cube)
    • Spectral Decomposition… — one iso-frequency volume per band (ID_SEISMIC_ATTR_SPECTRAL)
  • Create RGB Blend (3 selected)… — Composite three per-trace attribute volumes of the same source (Ctrl-click to select all three first) into one RGB colour section. See RGB blend (ID_SEISMIC_CREATE_RGB_BLEND)
