Analysis Tools

Analysis tools are available from the + action in a source's Analysis layers section in the Explore lens. Tool availability depends on the active source and image type.

Tool groups​

The Tools menu is grouped by workflow intent.

Exploratory analysis:

  • Color composite: create RGB or false-color composites.
  • Band math: generate spectral-index or custom formula layers.
  • Principal components analysis (PCA): reduce hyperspectral data into PCA components.
  • Endmembers extraction: extract candidate pure spectra from the image.
  • Reed-Xiaoli anomaly detection (RX): generate anomaly detection outputs.

Guided analysis:

  • Matched filter: detect a target reference spectrum.
  • Mixture-tuned Matched Filter (MTMF): run MTMF using a target reference spectrum.
  • Model inference: apply trained models to compatible HSI sources.

Import:

  • Upload external results: attach externally generated raster results to a source.

The same Tools menu also contains workspace resources such as Spectral libraries, Label types, Spectral indices, and Clarity AI when those features are available.

Choosing the target image​

Analysis tools run against the active image source. Select a source or layer before opening a tool. If no compatible image is active, the menu item is disabled.

Several tools let you choose the image data layer, such as raw, radiance, or reflectance. The default is usually the current layer, the active data layer, or the image's primary layer.

Wavelength ranges​

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

Use Workspace settings > Center wavelengths to set the default wavelength range for the workspace, or configure a source-specific range from the same section when an image is selected.

Reference spectra​

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

To add reference spectra:

  1. Open the Explore lens.
  2. Expand a source.
  3. Open Reference spectra.
  4. Click the add button and select a spectral signature from the library dialog.
  5. Click Add reference.

You can also open Tools > Spectral libraries to manage the spectral library directly.

Creating library spectra from labels​

After creating labels, right-click one or more labels and choose Add to spectral library. The dialog averages multiple selected signatures when needed and lets you choose the target spectral library.

Material identification​

Right-click a label and choose Identify material to compare the label's spectral signature against configured library spectra. Use Workspace settings > Material identification to control which libraries and chapters are searched and which preprocessing method is used.

After material identification runs, use the label context menu option to plot identified matches in the bottom spectral signatures panel.

Matched filter and MTMF​

Matched filter and MTMF require a target reference spectrum. The dialogs let you:

  • Choose the image data layer.
  • Select the target reference spectrum.
  • Optionally choose a background class from labels in the image.
  • Configure wavelengths.
  • Generate the result layer.

The generated result appears under Analysis layers. Select it to inspect statistics, display settings, and result metadata.

Endmember extraction​

Endmember extraction asks for:

  • The image data layer.
  • The number of endmembers.
  • The extraction method.
  • Optional wavelength filtering.

While a job is running, the source tree may show a condensed result group. Completed outputs appear as child layers that can be displayed, inspected, renamed, exported, or removed.

PCA​

PCA generation asks for:

  • The image data layer.
  • A result description.
  • The number of components.
  • Optional wavelength filtering.

Generated PCA layers can be selected in the source tree. Selecting a PCA layer opens a dynamic PCA tab in the bottom dock, where you can view and pin PCA charts.

Operation chain​

Some layer operations can be staged before being committed. When a staged chain exists, the bottom dock opens Operation Chain, and the Inspector shows chain controls. Commit or cancel the chain before starting unrelated edits when the pending operation should not apply.
