HDF and HDF-EOS Workshop XV
Last week I attended the HDF and HDF-EOS Workshop XV
in Riverdale, MD. The purpose of this workshop is to discuss HDF products, tools and libraries with engineers from The HDF Group
, scientists from NASA, NOAA and NSIDC, as well as vendors, like Exelis VIS
, who provide software tools to work with HDF.
I thoroughly enjoyed my time at the workshop. (I think I’m turning into a file format wonk.) I was particularly interested in learning more about HDF5 and netCDF-4 integration (netCDF-4 is built on HDF5). I’ve used the classic netCDF data model (with dimensions, variables and attributes) for a long time. Now, though, there’s the option to use the HDF5-compliant “extended” data model with groups and datasets. (IDL supports both; this is good.) I think it’ll be interesting to see how scientists who are used to the classic model adapt to this change. Several talks addressed the topic of HDF5/netCDF-4 interoperability.
The complete workshop agenda
is posted, along with abstracts and links to download each speaker’s slides. I gave a presentation on using IDL with Suomi NPP VIIRS data, similar to the ones I gave in March
, but here I tried to emphasize how HDF5 made it very easy to access the data in a VIIRS file. My slides
and example programs
are available for download.
