Info

Point Spectrum Generator TM , the target vector will already be entered in thesliders.Note that there is a check box at the bottom left side of the form entitled ‘InputTwo Spectra’. PANCROMA TM allows you to compute the Euclidean distance plotusing one input spectrum or alternatively two spectral If you want to analyze twospectra and compare them to the base image, check the box as is shown in thefigure above. If you want to analyze only a single spectrum, keep it un checked.Note that if you input two target spectra using Point Spectrum Generator TM , bothsets of spectra will be automatically input into the Spectral Criteria form.The ‘Set Upper Cutoff’ check box at the lower right side of the form is also veryuseful. Often there will be a small number of pixels with low reflectance values.These may not even be visible on a color contour plot, but will widen thereflectance range so that there is little color contrast in the plot. These can beclipped out using the ‘Set Lower Cutoff’ slider bar and can produce much bettercolor plots. An example of two such plots, one unclipped, and the second oneclipped are shown below.249
Click ‘OK’. The TOA Reflectance Data Form will become visible. Enter the SolarElevation Angle and the Acquisition Date and click ‘OK’.250
