Spectral Explorer overview

Spectral Explorer is a pane-based workspace for inspecting imagery, comparing layers, creating labels and masks, and running analysis tools against spectral data.

The workspace is organized as follows:

  • The command bar links to Explorer, Files, Datasets, and Models. It also provides Clarity search, the user guide, sharing, and Clarity AI when those features are available.
  • The project and workspace names in the center of the command bar open their respective switchers.
  • The left workflow rail contains Explore, Prepare, Label, Sites, Change, and Sources. Additional workflows may appear when preview features are enabled.
  • The center can contain one or more canvas panes. Use New canvas to add a canvas, then choose Map or Inspect for that canvas.
  • The right tool rail opens Inspector, Cube when a compatible cube is available, and Analysis.
  • The Analysis tray contains Spectral Signatures, Label Attributes, dynamic PCA · <name> tabs, and Operation Chain while an operation is staged.

Core concepts​

Sources​

A source is an image or remote item attached to the workspace. Source rows can represent uploaded HSI imagery, imported STAC items, shapefiles, overlay images, or other supported source types.

Select a source to inspect it. Double-click a source to focus a canvas on it. Right-click a source for actions supported by that source type.

Data layers and analysis layers​

Data layers are source products such as raw, radiance, reflectance, emissivity, or temperature data. The active data layer controls which product many analysis tools use.

Analysis layers are renderable results such as color composites, band math, PCA, matched-filter, MTMF, RX, endmember, model-inference, and imported raster outputs.

Workflows​

The same source tree remains available while the workflow changes which source content and controls are shown:

  • Explore shows analysis layers and reference spectra.
  • Prepare shows data layers and masks.
  • Label shows label sets and labeling controls.
  • Sources searches supported remote catalogs and adds imagery to the workspace.

Inspect and Map​

Inspect focuses on one reference source and displays its raster in image coordinates. It is useful for pixel inspection, labeling, and direct analysis.

Map places workspace sources and layers in geographic context. It is useful for comparing georeferenced imagery, reviewing remote-source search areas, and combining layers from multiple sources.
