This tab allows for calculating the spectral distance between every corresponding pixel of two :guilabel:`band sets`. The output is a raster containing the spectral distance of each pixel. Optionally, a threshold can be defined for creating a binary raster (0-1) of values below and above the threshold.
This tool supports virtual raster output; if the output file name ends
with .vrt then the output is created as virtual raster composed of as many
.tif files as the number of CPU threads defined in
:ref:`system_processing`; for large rasters this can speed up the process.
