Analysis tools

In the 0.100 preview, right-click a compatible source and select Run analysis…. You can also open Explore > Analysis layers, use the plus button with the Generate analysis layers tooltip, and choose Run analysis…. Select the tool in the shared dialog, then review its selected input layers. Availability depends on the source and image type; earlier environments may use individual generation dialogs.

Analysis menu​

Exploratory analysis:

  • Color composite: preview and save RGB or false color. In the 0.100 preview, single-image workspace analysis opens RGB Explorer.
  • Band math: generate a spectral-index or custom-formula layer.
  • Principal components (PCA): reduce hyperspectral data into principal components.
  • Endmember extraction: extract candidate pure spectra from an image.
  • RX anomaly detection: generate anomaly-detection output.

Guided analysis:

  • Matched filter: detect a target reference spectrum.
  • Mixture-tuned matched filter (MTMF): run MTMF against a target reference spectrum.
  • Deep learning: apply a trained model to compatible HSI data. See Inference results.

Use the source's Import raster action to attach an externally generated result; it is separate from the Run analysis dialog. Reference spectra, label settings, and Clarity AI also have separate entry points.

The submit button names the tool, such as Run PCA or Run matched filter. For a batch it also identifies the number of layers. Run and keep open submits without closing the dialog. Review compatibility and deselect unwanted targets before running; follow job status and verify completed results.

Destriping, ISOFIT, and orthorectification are source-context actions that create separate image versions. They are different from visualization and analysis layers.

Choose the target image​

Analysis starts with the image associated with the source whose action you used. From Files, select images and choose Run analysis to create a batch. An action is disabled when the source has no compatible image.

Several tools also let you choose a source data layer, such as raw, radiance, or reflectance. The current or primary image layer is selected by default when possible.

Configure wavelength ranges​

PCA, endmember extraction, matched filter, MTMF, RX, and reference-spectra workflows can use image-specific or workspace wavelength filters. Enter band ranges such as 0-100, 150-200, 222, or wavelength ranges in nanometers such as 400-700, 800-900.

Open Analysis from the right tool rail, open an analysis tab, and click Workspace settings to change Center wavelengths. An image-specific filter overrides the workspace default for that image.

Add reference spectra​

Reference spectra are library spectra linked to a workspace source. They appear in the source's Reference spectra section in Explore and can be plotted in Spectral Signatures.

To add a reference spectrum:

  1. Open Explore and expand a source.
  2. Expand Reference spectra.
  3. Click Add reference spectrum.
  4. Select a spectral signature in the library dialog.
  5. Click Add reference.

Create library spectra from labels​

After creating labels, right-click one or more labels and choose Add to spectral library. When several labels are selected, the dialog can create an averaged signature and lets you choose the target library.

Identify materials​

Right-click a label and choose Identify material to compare its spectral signature with configured library spectra. Use Workspace settings > Material identification to choose the libraries, chapters, and preprocessing method used for matching.

After identification finishes, use Plot identified material to add the matches to Spectral Signatures.

Run matched filter or MTMF​

Matched filter and MTMF require a target reference spectrum. Their dialogs let you choose the image data layer, target reference spectrum, optional background class, and wavelength range. Additional parameters appear when they apply to the selected method.

Use Run matched filter or Run MTMF to submit. The completed result appears in Analysis layers. Select it to inspect display settings, statistics, and metadata.

Extract endmembers​

Endmember extraction asks for the image data layer, number of endmembers, method, and wavelength range. Select Run endmember extraction. Completed outputs appear below the source as result layers.

Generate PCA​

Principal components (PCA) asks for the image data layer, result description, component count, and wavelength range. Select Run PCA. Select a completed layer to open its PCA · result name tab in the Analysis tray.

Commit an operation chain​

Some layer operations can be staged before they are committed. When a staged chain exists, Spectral Explorer opens Operation Chain in the Analysis tray. Review the preview, then commit or cancel the chain before starting an unrelated operation.
