The 2015 HDF workshop held during the ESIP Summer Meeting was a great success thanks to more than 40 participants throughout the four sessions. The workshop was an excellent opportunity for us to interact with HDF community members to better understand their needs and introduce them to new technologies. You can view the slide presentations from the workshop here.
From my perspective, the highlight of the workshop was the Vendors and Tools Session where we heard from Ellen Johnson (Mathworks), Christine White (Esri), Brian Tisdale (NASA), and Gerd Heber (The HDF Group) talk about new, and improved applications of HDF technologies. For example: Continue reading →
Please join us to learn about new HDF tools, projects and perspectives.
The HDF Group will be hosting a one-day workshop at the upcoming Federation for Earth Science Information Partners (ESIP) Summer Meetingin Asilomar, CA on Tuesday, July 14th.
There will also be an HDF Town Hall meeting on Wednesday afternoon, July 15th.
Please join us for any and all of the events. If you are unable to join us in person, you may participate through remote access. Remote access details will be made available through the ESIP meeting website. Questions? Contact Lindsay at email@example.com.
Fifteen years ago, NASA selected HDF as the format for the data products produced by NASA Satellites for the NASA Earth Observing System (EOS).
The HDF Earth Science Program is well aware of this important legacy. We focus on continuing support of U.S. environmental satellite programs (NASA Earth Observing Systemand Joint Polar Satellite System, JPSS), on-going quality assurance of the HDF libraries and helping data users access and understand products written in HDF. The HDF-EOS Information Center(#hdfeos) includes code examples in MATLAB, IDL, NCL, and Python, many driven by user questions. The site also provides information on other HDF tools.
NASA’s decision ensured a role for HDF in Earth Science and set an important precedent. HDF developers, along with the U.S. and other Earth Observing nations, developed a clear distinction between Earth Science Data Objects (grids, swaths, profiles…); the metadata required to describe them; and the HDF objects (datasets, groups, attributes, etc.) that make them up.
The critical realization was that communities like EOS needed conventions for describing Earth Science objects to enable using and sharing those objects. These conventions, termed HDF-EOS, have been used successfully in hundreds of NASA products that can be easily shared among multiple users using standard tools.
Many other Earth Science communities have used the powerful combinationof conventions and HDF. Continue reading →
