Project Interpretation Tree Structure

The Project Interpretation Tree displays geological interpretations and measurements organized hierarchically in the left panel "Interpretations" tab. This page documents all interpretation types in the exact order they appear, as defined in ProjectInterpViewBar::PopulateInterpTree().

Interpretation Structure Table​

The following table lists all interpretation categories in the Project Interpretation Tree in the exact order they appear. Click the links to access context menu commands and property documentation for each type.

Interpretation Tree Notes​

  • All items are top-level interpretation categories in the Project Interpretation Tree
  • Context Menu links show right-click operations for that interpretation type
  • Properties links show properties available when individual items are selected
  • Orientation data can be sorted by stratigraphic horizon or structural set using toolbar buttons
  • Items marked (development builds) may not appear in all VRGS versions
  • — indicates no dedicated documentation page exists (uses default operations)

Common Interpretation Uses​

Structural Interpretation​

  • Orientation - Structural measurements (bedding, fractures, cleavage)
  • Scan Lines - Fracture scan line surveys
  • Faults - Fault surface interpretations

Stratigraphic Interpretation​

  • Log Elements - Stratigraphic log units
  • Surfaces - Geological horizon surfaces (TIN Geosurfaces)
  • zone - Stratigraphic zone boundaries

Geometric Interpretation​

  • Polylines - 2D/3D interpreted line features (horizons, contacts, traces)
  • Geopolygon - Sedimentary body interpretations with facies
  • Sections - Cross-section panels through data

Auxiliary Data​

  • Palaeocurrent - Palaeocurrent indicators and flow directions
  • Flight Path - Camera paths for animations and geotours
  • Sketch Layers - Hand-drawn annotations and overlays
  • Measurements - General measurement data

Sorting and Organization​

The Interpretation Tree includes toolbar controls for organizing data:

Sort by Stratigraphy - Groups orientation measurements by stratigraphic horizon (picks)

Sort by Set - Groups orientation measurements by structural set (joint sets, bedding, etc.)

Expand/Collapse All - Expands or collapses all tree branches
