Claim 5:
6. A method for removing material from a rock body comprising:
producing rock type classifying data for the rock body by:
obtaining, at a processor for processing images, spectral data from a spectral measurement of a surface region of the rock body,
determining, by the processor, a first spectral ratio between two wavelength bands of the spectral data,
comparing, by the processor, the first spectral ratio to a threshold ratio, the threshold ratio predetermined to define spectral ratios that indicate an absorption feature associated with edge anomalies of at least one edge of a portion of the rock body,
in response to a determination, based on the comparing, that the first spectral ratio does not indicate an absorption feature associated with edge anomalies, determining, by the processor, a further spectral ratio between two further wavelength bands of the spectral data,
comparing, by the processor, the further spectral ratio with a corresponding diagnostic criterion to assess whether the surface region comprises a first rock type associated with the further spectral ratio and diagnostic criterion, and
classifying, by the processor, the first rock type present at the rock body surface based on the assessment of the further spectral ratio and diagnostic criterion and generating rock type classifying data for the rock body based on the classifying;

and
wherein the spectral measurement comprises images at discrete and narrow bands, including the wavelength bands for the first spectral ratio and the further spectral ratio.
