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
