foreground and background applications to process them successfully. Afterdownloading and unzipping your file, you should have a single RGB GeoTiffformat image. You can open it and inspect it by selecting ‘File’ | ‘Open’ to selectyour file and then selecting ‘Display Files’ | ‘Display One Color CompositeImage’. After inspecting, select ‘Close Graphics Window and Reset’. The firststep in transforming a GEOCOVER image is to decompose the RGB false colorimage into its corresponding band files.To do this select ‘File’ | ‘Open’ to select your file. Select ‘Decompose Bundles’ |‘Decompose Landsat Geocover – Spectral Transformer’ When the color imagedisplays, select ‘File’ | ‘Save Grayscale Image’ | ‘GeoTiff’. When prompted,supply a root file name. PANCROMA TM will save the three band files with a ‘2’,‘4’ and ‘7’ suffix, indicating the Landsat band designation.You can also do the decomposition manually by selecting ‘Display Files’ |‘Display Single Composite Image’. Check the ‘Generate Band Images’ checkbox and un check the ‘Generate RGB Color Composite Image’ check box. Noimages will be displayed in this case. When the processing stops, select ‘File’ |‘Save Grayscale Image’ | ‘GeoTiff’. When prompted, supply a root file name.PANCROMA TM will save the three band files with a ‘2’, ‘4’ and ‘7’ suffix,indicating the Landsat band designation.The next step is to transform the band2, band4 and band7 files into a syntheticnatural color RGB image. To do this, open the three band files, in the aboveorder (i.e. band 2 first) by selecting ‘File’ | ‘Open’ in succession. Now select‘Landsat GEOCOVER 742/321 Spectral Transformer’. PANCROMA TM will readin the three bands, process them, and then display the transformed RGB image.This image can be saved in the standard PANCROMA TM formats as usual.The standard image processing settings should work adequately in most cases.However, PANCROMA TM offers image processing utilities to improve theoutcome if this is needed. To access these utilities, check the ‘Activate ImageProcessing Routines’ check box on the main menu after selecting your threeband files. When the Image Processing Data Input Box appears, check the two‘742 Band Adjust’ check boxes.114
