Where are georeferencing coordinates stored in an image?
Image formats may store georeferencing coordinates in the header of the image file (Erdas IMAGINE files, MrSID images, GeoTIFFs, and so forth)or in an additional file called a header file .hdr (BIL, BSQ, and BIP). For example the header of the image myimage.bil would be myimage.hdr.
