3.4.5.9. Spectral distance

_images/spectral_distance_tab.png

Spectral distance

This tab allows for calculating the spectral distance between every corresponding pixel of two 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 System; for large rasters this can speed up the process.
