were matched using the ‘Rescale Landsat 14.25m to 15m’ Preprocessing utility.Finally, the reflectance band files were pan sharpened using a standard HSItransformation. The ELIN local optimization was switched off since this desertscene did not need this utility.SPOT Spectral Analyzer TMSpectral analysis using SPOT multispectral data proceeds the same as forLandsat, except that SPOT has only four multispectral bands as compared to thesix Landsat multispectral bands. Select ‘File’ | ‘Open and open four SPOT bandfiles, band1 (Green), band2 (Red), band3 (NIR), band4 (SWIR). (SPOT spectralband data is given in Section 29). Now select ‘Spectral Analysis’ | ‘SPOTSpectral Analyzer’ | ‘Four DN Bands’ | ‘<strong>Manual</strong> Method’. The Spectral CriteriaForm will be displayed as described in the previous section except only four bandfile data groups will be active. Afterwards, a second data entry box will bedisplayed for entering the appropriate TOA Reflectance data. The data entry issimilar to that described in Section 47 except that no binary float file option isoffered and the a color image is displayed as a default. In addition, you will haveto enter the SPOT Absolute Calibration Gain for each band. These vary fromimage to image so they must be obtained from the metadata for each SPOTscene. PANCROMA TM will compute the percentage of red pixels on the activepart of the image and display them in the Main Window dialog box as describedabove.NAIP Spectral Analyzer TMSpectral analysis using SPOT multispectral data proceeds the same as forLandsat, except that SPOT has only four multispectral bands as compared to thesix Landsat multispectral bands. Select ‘File’ | ‘Open and open four SPOT bandfiles, band1 (Green), band2 (Red), band3 (NIR), band4 (SWIR). (SPOT spectralband data is given in Section 29). Now select ‘Spectral Analysis’ | ‘SPOTSpectral Analyzer’ | ‘Four DN Bands’ | ‘<strong>Manual</strong> Method’ (or ‘Euclidean Distance’).Follow the instructions for these two methods outlined in the previous sections.The Spectral Criteria Form will be displayed as described in the previous sectionexcept only four band file data groups will be active. PANCROMA TM willcompute the percentage of red pixels on the active part of the image and displaythem in the Main Window dialog box as described above.ASTER Spectral Analyzer TMSpectral analysis using the six ASTER multispectral data proceeds the same asfor Landsat. Select ‘File’ | ‘Open and open the six ASTER SWIR band files,band4, band5, band6, band7, band8 and band9. (ASTER spectral band data isgiven in Section 30). Alternatively, you can also include the three Very NearInfrared (VNIR) bands (see note below).245
