Workspace Settings

Workspace settings control how Spectral Explorer displays signatures, identifies materials, and filters wavelengths for analysis.

Open workspace settings from either:

  • The settings button in the bottom dock.
  • The workspace or project name menu in the top bar, then Workspace settings.

Spectral signatures​

The Spectral signatures section controls the bottom Spectral Signatures chart.

Available chart settings include:

  • Show chart symbols.
  • Show all selection signatures instead of only the average.
  • Show chart crosshair.
  • Show spectral ranges.
  • Limit reflectance values between 0 and 2.
  • Show a line between points.
  • Show true RGB lines or the false-color bands used for the current render.
  • Show RGB bands only.

Use these settings when the chart is crowded, slow, or needs to align with the visible render bands.

Material identification​

The Material identification section controls label and endmember material matching.

Available settings include:

  • Spectral libraries & chapters: choose all libraries, selected libraries, or selected chapters.
  • Preprocessing method: choose the preprocessing applied before matching spectra.

Material identification is triggered from a label or endmember context menu with Identify material.

Center wavelengths​

The Center wavelengths section controls wavelength filtering for material identification, endmember extraction, reference spectra, matched filters, and related spectral workflows.

You can set:

  • An image-specific filter for the active image.
  • A workspace-level default filter for images without an image-specific filter.

Accepted formats:

  • Band ranges, such as 0-100, 150-200, 222.
  • Wavelength ranges in nanometers, such as 400-700, 800-900.

Clear the image-specific filter to fall back to the workspace setting.
