have to rationalize the file sizes. The resolution of the VNIR bands is 15m/pixelwhile that of the SWIR bands is 30m/pixel. The file sizes can be rationalizedeither by resampling the VNIR bands down or interpolating the SWIR bands upusing the PANCROMA TM Resize utilities. Interpolating up is recommended inorder to avoid loss of information from the ASTER scene.IMPORTANT NOTE: PANCROMA TM wants the ASTER data in GeoTiff format.You may have to convert your data using the free MultiSpec utility beforeprocessing.IMPORTANT NOTE: PANCROMA TM can handle Digital Globe and World View2data in either 8-bit or 16-bit format.It may be desirable to adjust the data span for the Euclidean Distance display.Often a small number of “flyer” Euclidean Distance values can skew the plot sothat there is not very much discrimination. An example of this situation is shownbelow.The plot can be improved by lumping the larger Euclidean Distances together.To do so, check the ‘Set Upper Cutoff’ check box at the lower right hand cornerof the Spectral Criteria Form.254
