Declaration: SpecRangeOfSpdcs(SpectralType : TLayerType; var RangeLow, RangeHigh: double);
The procedure SpecRangeOfSpdcs checks all currently loaded spectral descriptors which require spectra of the type specified by the parameter SpectralType and returns the range of spectral values required for the correct function of these spectral descriptors in the parameters RangeLow and RangeHigh. Setting the parameter SpecType to ctUndefined forces the procedure to check all spectral descriptors regardless of the spectral type they are referring to.
