Description
Szip compression software, providing lossless compression of scientific data, has been provided with HDF software products as of HDF5 Release 1.6.0 and HDF4 Release 2.0.
Szip is an implementation of the extended-Rice lossless compression algorithm. The Consultative Committee on Space Data Systems (CCSDS) has adopted the extended-Rice algorithm for international standards for space applications. Szip is reported to provide fast and effective compression, specifically for the EOS data generated by the NASA Earth Observatory System (EOS). It was originally developed at the University of New Mexico (UNM) and integrated with HDF4 by UNM researchers and developers.
The primary gain with Szip compression is in the speed of processing. Szip also provides some advantages in compression ratio over other compression methods shown here. These results, including the data presented in the graphs below, are from tests conducted by Pen-Shu Yeh, et al., with the HDF4 Szip integration.
