wxIClass is a wxGUI extension.

Generates spectral signatures for an image by allowing the user to outline regions of interest. The resulting signature file can be used as input for i.maxlik or as a seed signature file for i.cluster. (cited from i.class manual)

wxIClass is available in GRASS 7 from the menu

File -> Imagery -> Classify image -> Interactive input for supervised classification

wxIClass currently allows to:

  • create training areas (using vector digitizer)
  • show histograms for each band and class (category)
  • show coincidence plots for each band
  • show raster cells that match training areas (within the number of standard deviations specified)
  • specify color of class
  • write signature file
