Convex hull and continuum-removal

Calculate convex hull and continuum-removed raster layers.

Usage:

  1. Open the algorithm from the processing toolbox.

  2. Select a raster layer and define the X unit, then click run.

    usr_section/usr_manual/processing_algorithms/raster_analysis/source/usr_section/usr_manual/processing_algorithms_includes/raster_analysis/img/hull_removal.png
  3. The output raster can be found under Rasters in the Data Source Panel

Parameters

Raster layer [raster]

Raster layer with spectral profiles.

X units [enum]

The x units used for convex hull calculations. In case of Nanometers, only spectral bands are used.

Default: 0

Outputs

Output convex hull raster layer [rasterDestination]

Raster file destination.

Output continuum removed raster layer [rasterDestination]

Raster file destination.
