This tutorial is designed for anyone who wants to access NASA HDF and HDF-EOS data with tools and software packages primarily developed for other data formats such as netCDF.
In the past three years, The HDF Group developed a few tools aiming to improve the usability of NASA HDF and HDF-EOS data files. This tutorial will demonstrate how to use these tools. The tools are the H4CF Conversion Toolkit, the HDF-EOS5 Augmentation Tool, the HDF-EOS2 to netCDF-4 Converter, HDF-EOS5 to netCDF-4 Converter, and HDF-EOS2 Dumper.
The H4CF Conversion Toolkit includes the H4CF Conversion Library which provides APIs to access the HDF4/HDF-EOS2 objects following the CF conventions. In addition, the toolkit also provides the HDF4/HDF-EOS2 to netCDF-3 and netCDF-4 classic converters based on the library. For more information, visit http://hdfeos.org/software/h4cflib.php.
The HDF-EOS5 Augmentation Tool augments an existing HDF-EOS5 file so that the augmented file can be accessed by both the HDF-EOS5 library and the netCDF-4 library. For more information, visit http://hdfeos.org/software/aug_hdfeos5.php.
We also provide an option in the HDF4 to HDF5 conversion tool, which can convert an HDF-EOS2 file to an HDF5 file that can be accessed by the netCDF-4 library.
The HDF-EOS5 to netCDF-4 Converter converts an HDF-EOS5 file to an HDF5 file that can be read by the netCDF-4 libraries. For more information, visit http://hdfeos.org/software/convert_hdfeos5.php.
The HDF-EOS2 Dumper dumps useful information of an HDF-EOS2 file. For example, this tool can dump latitude and longitude data for all grids and swaths. For more information, visit http://hdfeos.org/software/eosdump.php.
Bring questions and comments for these tools to the workshop.
