[PS3-5] Image description files

The image data stored in a binary data format (BIL, BIP, BSQ) is accompanied by description files that contain a set of entries describing the image data, including acquisition time, image size, statistics, map projection, pixel digital numbers, product type, etc. This general image or product information is stored in a form of header embedded in the image file or provided in the separate file (.hdr) or metadata in XML. There are numerous image file formats, the more common are TIFF (GeoTIFF), bitmap (.bmp), JPEG (.jpg, .jpeg, JPEG2000), HDF, Raw (.raw), Extensible N-Dimensional Data Format (NDF).
