Sources and layers

Source and layer controls live in the source tree shown by the Explore, Prepare, and Label workflows. Each workflow shows a different part of the same workspace sources.

Add imagery to a workspace​

Use the entry point that matches the data:

  • In an empty workspace, click Import Data to upload local data and attach it to the workspace.
  • Open Sources to search Planetary Computer or configured STAC Catalogs, preview remote items, and add them to the workspace.

After data is attached, Spectral Explorer creates a source row and exposes the renderable layers available for that source.

Use source rows​

Source rows are the top-level items in the source tree.

  • Click a source to select it and open Inspector.
  • Double-click a source to focus the active canvas on it.
  • Right-click a source to open actions supported by its type and state.
  • Drag source rows to reorder them when the current view supports ordering.
  • In Inspect, use the source selector to set the reference source.

Depending on the source, its context menu can include Run analysis…, Explore RGB, Open 3D cube, Open parent folder, export, retry, and removal actions. Model inference is under Run analysis… > Deep learning.

Explore analysis layers​

Explore contains renderable analysis layers. These can include color composites, PCA rasters, band math, matched-filter, MTMF, RX, endmember, model-inference, and imported raster results.

Use the visibility controls beside a layer or result group to add or remove it from the active canvas. Right-click a layer for available actions such as Add to layers, Remove from layers, Rename layer, Send to top, Send to bottom, export, retry, or result removal. The exact actions depend on the layer type and state.

Prepare data layers and masks​

Prepare contains processing-oriented source data:

  • Data layers lists products such as raw, radiance, reflectance, emissivity, or temperature data. The selected product is used by analysis tools that ask for an image layer.
  • Masks lists source image masks. A mask can constrain processing and can also be shown as an overlay.

Inspect properties​

Select a source, layer, result group, mask, label, or remote-item preview, then open Inspector from the right tool rail.

For a layer, Inspector contains the display settings supported by that layer, such as opacity, color map, stretch, component mapping, class colors, statistics, and result metadata.

While editing an RGB draft, this panel is titled RGB Explorer and contains the draft's composition and save controls. Select a source again to inspect its metadata. See Generate color composites.

Compare image versions — 0.100 Preview​

Correction outputs appear as separate image sources grouped under N versions. Expand the group and select the intended version before running another analysis. The original remains available; a newly published version does not silently replace your selection. See Image versions and corrections.

Review or change the selected image's sensor under Inspector > Details. See Sensors and RGB defaults.

Create or recolor a composite​

To create an RGB or false-color composite in the 0.100 preview, right-click an image source and choose Explore RGB, or open Run analysis…, choose Color composite, and select Open RGB Explorer. Earlier releases may use a generation dialog. See Generate color composites.

To recolor an existing scalar layer, select it and use its display controls in Inspector. Continuous layers use color-map and range controls; classification layers use class colors when available.
