Reading and Analyzing Mission HDF5 Files in the Cloud - ESIP Cloud Computing Cluster Session August 28 at 10am PT / 1pm ET

Reading and Analyzing Mission HDF5 Files in the Cloud

We are excited to have JP Swinski and Rachel Wegener present at the next ESIP Cloud Computing Cluster meeting on HDF5 Files in the Cloud.

Topic: Reading and Analyzing Mission HDF5 Files in the Cloud
When: Monday August 28th, 10:00-11:00 am PT / 1:00-2:00 pm ET / 7pm CEST
Where: Find joining information on ESIP Community Calendar

Speakers: JP Swinski (Goddard Space Flight Center) and Rachel Wegener (PhD student at University of Maryland)


HDF5 is a flexible scientific data format which is used for many high-value Earth observation datasets, such as the ICESat-2 standard data products. However, the HDF5 library and tools were designed for local file systems, and to date have not performed well in cloud environments. The ICESat-2 program funded the development of an on-demand data service called SlideRule. SlideRule needed performant access to HDF5 files in S3, and in response, developed the HDF5 Cloud-Optimized Read-Only Library (h5coro). JP will present the key features of h5coro that enable performant cloud access to HDF5 data. Rachel Wegener will present an in progress effort to integrate h5coro as an xarray backend, and will discuss the need for more robust data formats for Icesat-2 point cloud data.
