3.4.5.9. Spectral distance (complete interface)

_images/spectral_distance_tab.png

Spectral distance

This tab allows for calculating the spectral distance between every corresponding pixel of two band sets. It is loaded only if the Simplified interface is not enabled.

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 System; for large rasters this can speed up the process.
