32. RGB Color Image Batch File Processing_______________________________________________________________PANCROMA TM provides a utility for processing GeoTiff or L1G files batch-wise.That is, you can queue up as many Landsat (or SPOT) band file sets as youwant and then instruct PANCROMA TM to construct the RGB color compositeimages. In order to do this, you must of course download the sets of band datanecessary for constructing the images. It is not necessary that the files be allGeoTiff type or all L1G type. (Of course each band file for a particular imagemust match.) So for example, you could download the following six files into adirectory:p001r051_7t20011104_z20_nn10.tifp001r051_7t20011104_z20_nn20.tifp001r051_7t20011104_z20_nn30.tifandL71004071_07120000412_B10.L1GL71004071_07120000412_B20.L1GL71004071_07120000412_B30.L1GEach set of L1G files must have the accompanying metadata file and themetadata file must reside in the same directory as the associated band files. Inorder to process the two groups batch wise, select ‘Display Files’ | ‘BatchProcess RGB True Color Composite ETM+’ | ‘Batch Process’. You will beprompted to enter some data by the appearance of a dialog box. Two of thebuttons will be enabled. Choose ‘Add File’ to add band files to the queue and‘Cancel’ to interrupt the operation.When you select the ‘Add File’ button a familiar Windows open dialog box willappear that will allow you to browse to the directory where your files are stored.After doing so, select the first blue band and select ‘Open’ . The first band filewill be added to the queue and its name will appear in the text box of the dataentry dialog box.87
