Easy access to the NASA HDF products via OPeNDAP’s Hyrax

MuQun (Kent) Yang, The HDF Group

Many NASA HDF and HDF5 data products can be visualized via the Hyrax OPeNDAP server through Hyrax’s HDF4 and HDF5 handlers.  Now we’ve enhanced the HDF5 OPeNDAP handler so that SMAP level 1, level 3 and level 4 products can be displayed properly using popular visualization tools.

Organizations in both the public and private sectors use HDF to meet long term, mission-critical data management needs. For example, NASA’s Earth Observing System, the primary data repository for understanding global climate change, uses HDF.  Over the lifetime of the project, which began in 1999, NASA has stored 15 petabytes of satellite data in HDF which will be accessible by NASA data centers and NASA HDF end users for many years to come.

In a previous blog, we discussed the concept of using the Hyrax OPeNDAP web server to serve NASA HDF4 and HDF5 products.  Each year, The HDF Group has enhanced the HDF4 and HDF5 handlers that work within the Hyrax OPeNDAP framework to support all sorts of NASA HDF data products, making them interoperable with popular Earth Science tools such as NASA’s Panoply and UCAR’s IDVThe Hyrax HDF4 and HDF5 handlers make data products display properly using popular visualization tools.  Continue reading

Worried about your unlimited data plan bills? Cut them with OPeNDAP

Joe Lee, The HDF Group

Sprint has recently hit the airwaves with a promotion claiming that they will cut your data bill in half.  But there’s no free lunch in this connected world we live in. Unlimited data plans always come with a steep price tag.

While the internet has been around awhile, there has recently been an explosion of data – email, the World Wide Web, social media, cloud computing, mobile apps for everything, and Big Data.  At the same time, the overall global population of people using the internet has skyrocketed, as has the “Internet of Things.” Getting around can be a challenge.

The overcrowded and congested internet will continue to throw more data on us. Consequently, getting the right amount of the right data can also be a great challenge.  When it’s delivered over the internet, getting the right amount of data also helps ensure that your data delivery time will be dramatically shortened, and your data delivery costs minimized.  Continue reading
