My area of interest for this image is on the eastern coast of South America(Argentina) around latitude -14.9467068 and longitude -70.6615959 (upper leftcorner of the image). So the next step is to select ‘Band Combination’ | ‘SubsetImages’ | ‘Subset Four Bands’. PANCROMA TM will begin parsing and decodingthe files. The progress bar and the text screen will inform you of progress.When PANCROMA TM has successfully decoded the files you will be presentedwith an image window and a data entry screen as shown in the figure below.You can select your subset area either by clicking on the corners using themouse (in which case the pixel coordinates will appear in the Manual Data EntryPanel), keying in latitude and longitude coordinates when available (all LandsatTIF and L1G format files as will as SPOT and ASTER TIF.) or else you canchoose to enter the corners using the rubber band box. The pixel coordinatemethod allows you to select a point and then scroll using the slider bars to selectthe second point. When you use the rubber band box, your selection is confinedto the visible screen. The pixel coordinate method also lets you make as manyattempts as you like before selecting ‘Enter’. If your subset area is not too large,it is OK to leave the ‘Display Subset Images’ check box checked. With largersubsets that approach the full size of the image it will be necessary to uncheck304
