natural color image, first load the VNIR image by selecting select ‘File’ | ‘Open’.Check the ‘Generate Band Images’ check box. The select ‘Display Files’ |’Display One Color Composite Image’ from the menu.Doing so will automatically generate both the false color image (as downloadedfrom the Data Pool) and the three grayscale band files. Save the band files byselecting ‘File’ | ‘Save Grayscale Image’. Now you can create a natural colorimage by selecting the ‘Band Combination | Generate RGB True ColorComposite from ASTER’ menu selection. See Section 48 of this <strong>Manual</strong> forfurther instructions in using the special image processing utilities needed toproduce acceptable synthetic RGB color composite images from ASTER.ASTER L1B data is also available for most of the earth for a modest fee. Youcan download the data from the NASA WIST website. At the time of this writing,the cost for an ASTER multispectral scene is $80 USD.97
36. Working with Formosat-2 Data________________________________________________________________FORMOSAT-2 is an Earth observation satellite operated by the National SpaceOrganization (NSPO) of the Republic of China (Taiwan). It is a high-resolutionphotographic surveillance satellite with a daily revisit capability.

Resolution is 8 meters/pixel for the multispectral bands and2m/pixel for the panchromatic band. The multispectral data must be unbundledinto separate band files for processing. (The panchromatic band is offered in aseparate file.In order to perform the extraction, select ‘File’|’Open’. Then select ‘DecomposeBundles’. Select ‘Decompose Four File Digital Globe/GeoEye/Formosat-2Bundle’ menu selection. You will be prompted via a Save Dialog box to enter anoutput file name. A numerical suffix will be added to whatever name you select,for example ‘outputfile1.tif’, outputfile2.tif, etc. When you accept the file name,PANCROMA TM will decode the bundle file and write individual band files to the98
