Annotations Context Menu

Commands available when right-clicking annotation objects in the Data Tree. Annotations include labels, text annotations, and overlay layers used for documenting, marking, and presenting information in the 3D scene.

Label Items​

Commands available when right-clicking Label objects (text annotations positioned in 3D space).

Goto​

Menu name: Goto Tooltip Move the 3D view to the label location.

What it does Centres and zooms the 3D view on the selected label, positioning the camera to show the label and its immediate surroundings clearly. The view is adjusted to bring the label into focus, making it easy to locate annotated features.

When to use it

  • Locating specific annotated features
  • Reviewing documentation labels systematically
  • Navigating to marked points of interest
  • Finding features referenced by label text

Notes Labels are typically positioned at specific 3D coordinates marking geological features, measurement locations, or points of interest. Goto centres the view on the label's anchor point. Useful for navigating through annotated datasets where labels mark key locations. Label text remains visible in the view after navigation.

Delete​

Menu name: Delete Tooltip Permanently remove label from project.

What it does See Delete in Shared Commands for complete documentation. Permanently removes the selected label from the project. The annotated feature itself is not affected - only the label text and position are removed.

When to use it

  • Removing obsolete annotations
  • Cleaning up temporary labels
  • Deleting incorrect or duplicate labels
  • Updating documentation after interpretation changes

Notes Operation cannot be undone. The feature that was labelled remains in the project - only the text annotation is removed. If the label marks an important feature, ensure the information is documented elsewhere before deletion.

Overlay Groups​

Commands available when right-clicking Overlay Groups (collections of 2D overlay layers).

New Discrete Layer​

Menu name: New Discrete Layer Tooltip Create new discrete (categorical) data overlay layer.

What it does Creates a new overlay layer for displaying discrete (categorical) data as 2D overlays in the 3D scene. Discrete layers contain classified data with distinct categories (e.g., land use types, geological units, classification results) rather than continuous numeric values. Each category is assigned a unique colour for visualisation.

When to use it

  • Displaying classification results
  • Showing categorical spatial data
  • Overlaying interpreted geological units
  • Visualising discrete attribute distributions
  • Presenting landcover or land use maps

Notes

Discrete vs Continuous

Discrete layers contain categorical data with distinct classes (e.g., "sandstone", "limestone", "shale"). Each category has a colour assignment. Continuous layers contain numeric data spanning a range (e.g., elevation, temperature, concentration) displayed with colour gradients.

Discrete layers are typically rendered with flat colours per category, creating clear boundaries between classes. Suitable for classification schemes, geological maps, interpreted zones. Categories can be defined after layer creation by assigning values and colours. Common sources include raster classification results, interpreted polygons, or categorical attribute exports.

New Continuous Layer​

Menu name: New Continuous Layer Tooltip Create new continuous (numeric) data overlay layer.

What it does Creates a new overlay layer for displaying continuous numeric data as 2D colour-mapped overlays in the 3D scene. Continuous layers contain data spanning a numeric range (e.g., elevation, gradient, thickness, density) visualised using colour ramps that interpolate smoothly between values.

When to use it

  • Displaying elevation or bathymetry
  • Showing scalar field values (thickness, concentration, intensity)
  • Visualising gradients or derived metrics
  • Overlaying geophysical data (gravity, magnetics)
  • Presenting heat maps or density maps

Notes Continuous layers use colour ramps (gradients) to map numeric values to colours. Standard colour schemes include rainbow, grayscale, blue-white-red (diverging), and terrain (elevation). Colour scale can be adjusted to highlight specific value ranges. Supports transparency for blending with underlying geometry. Common data sources include DEMs, interpolated point data, raster calculations, or continuous attribute exports.

Overlay Items​

Commands available when right-clicking individual Overlay items (layers).

Test​

Menu name: Test Tooltip Test overlay rendering and display.

What it does Executes diagnostic test of the overlay layer's rendering pipeline and data integrity. Verifies that the layer can be displayed correctly, data ranges are valid, and rendering parameters are properly configured. Reports any issues encountered (missing data, invalid ranges, rendering errors).

When to use it

  • Troubleshooting overlay display problems
  • Verifying overlay data loaded correctly
  • Diagnosing rendering errors
  • Checking overlay configuration before presentation

Notes

Development Feature

This command may be a development/diagnostic tool and might not be present in release builds. It tests internal rendering mechanisms rather than performing user-visible operations.

Test results typically appear in a diagnostic dialogue or log. Common issues detected include missing georeferencing, invalid data ranges, corrupted raster data, or incompatible colour mappings. If test fails, check data source and overlay configuration.

Set As Active​

Menu name: Set As Active Tooltip Set this overlay as the active layer for operations.

What it does Designates the selected overlay as the "active" overlay layer. The active layer is used as a reference by various operations and may receive special display treatment (e.g., highlighted in layer list, preferential display order). Only one overlay can be active at a time across all overlay groups.

When to use it

  • Before operations requiring a reference overlay
  • When editing or adjusting overlay parameters
  • For workflows that reference the active layer
  • Setting primary overlay for multi-layer displays

Notes Active status controls which overlay receives editing operations, attribute queries, or export commands when multiple overlays are present. Some analysis operations automatically apply to or reference the active overlay. Active overlay may be displayed with higher opacity or in front of inactive overlays. Useful when working with multiple co-registered overlay layers (e.g., multiple geophysical datasets over the same area).
