Currently no auxiliary data or georeferencing information is extracted from HDF files.
RI8 files consist of 8-bit run length encoded, or uncompressed imagery. SDS files may contain 8-bit, 16-bit, or floating point image channels (floating point channels have not been tested). NASA-generated PAL data is also supported. The Vset extensions to HDF files are not supported.
The HDF format was developed by the National Center for Supercomputing Applications (NCSA), which maintains a library for accessing HDF files and various applications for displaying and operating on HDF files.
Export of HDF files is supported. These files are exported with a type of "HDF".
All image data types may be exported to HDF files; however, no bitmaps, LUTs, PCTs, vectors or georeferencing may be exported. Exporting more than one data type in a single HDF file is not currently supported. HDF files may have associated georeferencing information stored in an .aux file.
