Group: Summary

   Notice to Data Users: The documentation for this data set was provided solely 
   by the Principal Investigator(s) and was not further developed, thoroughly 
   reviewed, or edited by NSIDC. Thus, support for this data set may be limited.

   This data set consists of a sampling of each type of Hierarchical Data Format 
   version 4 (HDF4) data that are archived at the eight National Aeronautic and 
   Space Administration (NASA) Earth Science Data Centers (ESDCs). The data were 
   sampled for a collaborative study between The HDF Group, the Goddard Earth 
   Sciences Data and Information Services Center (GES-DISC), and the National 
   Snow and Ice Data Center (NSIDC) in order to assess the complex internal byte 
   layout of HDF files. Based on the results of this assessment, methods for 
   producing a map of the layout of the HDF4 files held by NASA were prototyped 
   using a markup-language-based HDF tool. The resulting maps allow a separate 
   program to read the file without recourse to the HDF application programming 
   interface (API) (Duerr et al. 2009). Data products selected for the study, and 
   a table summarizing the results, are available via FTP.
