Landsat Reflectance Point Spectrum Generator TMThe Landsat Reflectance Point Spectrum Generator TM operates very much likethe DN Point Spectrum Generator TM except it accepts 16-bit Landsat Reflectanceband files instead of the 8-bit DN files described in the previous section. To useit, open six multispectral band files as described in the previous section. Thenselect ‘Spectral Analysis’ | ‘Landsat Point Spectrum Generator’ | ‘Six ReflectanceBands’. The Point Spectrum Data Entry box and band1 image will be presentedas described in the previous section. Unlike the DN PSG, it is not necessary toinput the Solar Elevation Angle and Acquisition Date as the reflectance have ofcourse already been computed and are stored in the input files. The ReflectancePSG is otherwise exactly as described above.The NIR band is also used for point selection for Landsat reflectance data for thereason cited above.Landsat Reflectance/TIR Band Point Spectrum Generator TMThe Landsat Point Spectrum Generator TM accepts six 16-bit Landsat Reflectanceband files (bands 1, 2, 3, 4, 5 and 7) plus the thermal infrared (TIR) band 6, for atotal of seven bands. Using the thermal band adds an additional discriminatorthat can be useful for classifying certain types of targets. To use it, open sixmultispectral band files as described in the previous section, plus the thermal228
