The HDF Group
The software that The HDF Group has developed for the JPSS project is described on this pagebelow.
The HDF Group developers created and currently support the following tools for the JPSS project:
This prototype tool allows users to access their data files using different parameters such as chunking sizes, compression methods, access patterns, and chunk cache settings. The tool provides performance statistics to help users to find the optimum parameters to create and sccess their HDF5 files.
JPSS data is distributed in HDF5 files containing raw data and indexing metadata that allows fast access to the raw data. The HDF Group continues to develop software libraries and tools to improve access to this data. As part of this effort, The HDF Group has created a library of C and Fortran routines to access and manipulate data referenced by object and region references and to access and manipulate data packed into integer values. We continue to seek feedback from JPSS applications developers and users, as well as from the wider HDF5 community, and will improve this library as requested.
The HDF Group is maintaining HDF5 software on the following systems used by JPSS:
The latest versions of documentation for software developed for the JPSS project are available for download. See the list below.
For general information on each tool, see the Software page.
