Please see The HDF Group's new Support Portal for the latest information.
The software that The HDF Group has developed for the JPSS project is described on this page.
Tool Development
The HDF Group developers created and currently support the following tools for the JPSS project:
- h5edit
- h5augjpss
- nagg
- Chunking and Compression Performance (CCP) Tool
With h5edit, users can edit attributes in an HDF5 file.
With h5augjpss, users can modify a JPSS product file to make it accessible by netCDF-4 based applications.
The nagg tool was created to provide individual users the ability to rearrange product data granules from downloaded files into new files with aggregations or packaging that are better suited as input for a particular application.
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.
Library Development
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.
Supported Systems
The HDF Group is maintaining HDF5 software on the following systems used by JPSS:
- Linux 32 and 64-bit
- AIX 5.3 and 6.1
- Windows 32 and 64-bit
- Mac Intel OS X 10.5 and later
