these parameters are not specified. If you omit one of those parameters, the complementary one will be calculated based on the file size (taking into account header size, number of bands and data type). If you omit both parameters, the statistical approach will be used. Utility will compute correlation coefficient between two lines at the image center using several appropriate line sizes and the highest absolute value of the coefficient will indicate the right line size. That is why you should be cautious with the very large images, because guessing process may take a while (depending on your system performance). Of course, the utility can’t guess the header size, number of bands and data type, so it should be specified manually. If you don’t know anything about your image, just try with the several combinations of those options.</p> <!-- INDENTATION --> <p>There is no magic, it is just a mathematical statistics, so it can be wrong in some cases.
