I have lat/lon bands for my images, which provides lat/lon values for the upperleft corner of each pixel (not the centre). The pixel size is not regular, so I do not have pixel centre coordinates. I would like to georefence the images using these lat/lon bands. Nevertheless, I supose that the process of building a GLT file from these lat/lon bands considers lat/lon values as if they were pixel centre coordinates. If this is true, this fact would generate a georeferencing error when images are georeferenced from this GLT file. How could I solve the problem?
