Info

the utility, you must start with two three-file data sets, for example a Landsatband1, band2 and band3 Reference file and a band1, band2 and band3 Adjustfile. There must be at least some common area shared between the two datasets. The band files must also be in GeoTiff format. To get started, open threeband files (either the Reference or Adjust group) by selecting ‘File’ | ‘Open’ andopening three files from the same data set in series. Continue opening threemore files, for example the files from the Adjust data set if you opened theReference set first.You should now have six band files opened. Now select ‘Band Combination’ |‘Subset Images’ | ‘Subset Six Bands’. When the subset data entry box appears,just click on ‘Enter’. PANCROMA TM does the rest after that. If all goes well, youshould see your six registered images appear after a bit of computation. You cansave all six files by selecting ‘File’ | ‘Save’ and typing in a base file name.PANCROMA TM will add a numerical suffix to the base file name, numbering theoutput files in the same order that you input them. You are now ready to gap fill,cloud mask, or otherwise process the registered images.The example files below illustrate how the utility works. The first image isLandsat file L71001076_07619991115_B30.TIF, Row 76 Path 1 acquired overAnotfagasta, Chile. The second image is Landsatp001r076_7t20000525_z19_nn30.tif, Row 76 Path 1 of the same area. The firstimage has 6991 rows and 7851 columns and is a 30m per pixel image. Thesecond image has 7641 rows and 8704 columns and is a 28.5m per pixel image.137
The next two images are the registered versions of the two images, having thesame corner coordinates, same scale, and same row and column counts.138
