Now select ‘Spectral Analysis’ | ‘ASTER Spectral Analyzer’ | ‘Six DN Bands’ |‘Manual Method’ or alternatively ‘Spectral Analysis’ | ‘ASTER Spectral Analyzer’ |‘Nine DN Bands’ | ‘Manual Method’ The Spectral Criteria Form will be displayedas described in the previous Landsat section. Afterwards, a second data entrybox will be displayed for entering the appropriate TOA Reflectance data. Thedata entry is the same as described in Section 47 except that no binary float fileoption is offered and the a color image is displayed as a default. PANCROMA TMwill compute the percentage of red pixels on the active part of the image anddisplay them in the Main Window dialog box as described above.IMPORTANT NOTE: If you decide to use the three ASTER Very Near Infrared(VNIR) bands in addition to the six Short Wave Infrared (SWIR) bands, you willhave to rationalize the file sizes. The resolution of the VNIR bands is 15m/pixelwhile that of the SWIR bands is 30m/pixel. The file sizes can be rationalizedeither by resampling the VNIR bands down or interpolating the SWIR bands upusing the PANCROMA TM Resize utilities. Interpolating up is recommended inorder to avoid loss of information from the ASTER scene.IMPORTANT NOTE: PANCROMA TM wants the ASTER data in GeoTiff format.You may have to convert your data using the free MultiSpec utility beforeprocessing.EO-1 ALI/Hyperion Spectral Analyzer TMSpectral analysis using the nine EO-1 ALI multispectral or Hyperion hyperspectaldata proceeds the same as for Landsat except that three more files must beinput. Select ‘File’ | ‘Open and open the nineEO-1 ALI band files, band2, band3,band4, band5, band6. band7, band8, band8 and band10. (EO-1 spectral banddata is given in Section 31). Now select ‘Spectral Analysis’ | ‘EO-1 ALI SpectralAnalyzer’ | ‘Nine DN Bands’ | ‘Manual Method’. The Spectral Criteria Form willbe displayed as described in the previous Landsat section. Afterwards, asecond data entry box will be displayed for entering the appropriate TOAReflectance data. The data entry is the same as described in Section 47 exceptthat no binary float file option is offered and the a color image is displayed as adefault. 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.WorldView2 Spectral Analyzer TMSpectral analysis using the eight WorldView2 multispectral or data first requiresthat the eight WV2 multispectral bands be decomposed from the singlePlanarConfiguration=2 (non-contiguous) GeoTiff file into eight individual bandfiles. To do this, open the single bundled GeoTiff file as issued by DigitalGlobe®by selecting ‘File | Open’. Then select ‘Display Files’ | ‘Decompose Eight File246
