I need to load 4 to 6 full disk satellite images at 5 km resolution and then compare patches of the images. (2500 X 2500 pixels). I can load two of these, but then the memory overflows with mx384. It appears that loading replaces all the 8 bit pixels with reals or doubles. Is there a way to keep these arrays as bytes? The comparisons occur on small areas within the images (100X100km or 20X20 pixels) which are extracted with image.resample(domain..). That seems to work. But I need to step across the full disk image, resampling each piece so I can not afford to reload the 6 images for each matching step (each cloud). Any suggestions would be appreciated. G.
