Exploring Earth Science Data with Giovanni (the Next Generation)
Wednesday, November 20, 2013
Building 3 Auditorium - 11:00 AM
(Coffee and cookies at 10:30 AM)
For more than a decade, users of Earth science remote sensing data have been using Giovanni (Geospatial Interactive Online Visualization ANd aNalysis Infrastructure) to explore the data online. Developed at the Goddard Earth Sciences Data and Information Services Center, with input from many of GFSC's own Earth scientists, Giovanni provides many data summarization, analysis and visualization capabilities. These features enable users to examine the data without having to download the original files, learn complicated data formats, and write code for basic display and analysis. Thus, scientists can trim weeks or even months off the early data reconnaissance and preprocessing phases of a science project. Now, Giovanni is undergoing a re-architecture to enable even more interactive data exploration, with order-of-magnitude performance increases, browser-based interactive plotting and new functionality such as seasonal data visualizations.
Christopher Lynnes has been designing and implementing information systems at NASA/GSFC since 1991. He led the software development for the Version 0 GSFC Distributed Active Archive Center, later becoming its Chief Systems Engineer and Information Systems Architect. He has led the architecture and development of science data archive systems (S4PA), data processing systems (S4PM), and search tools (WHOM, Mirador, Simple Subset Wizard). He also works extensively on interoperability issues within both NASA and the Federation of Earth Science Information Partners (ESIP), where he has spearheaded community efforts to develop a federated search framework and an Earth Science Collaboratory. He has won the GSFC Award for Excellence in Information Science and Technology (2001) and the ESIP President's award (2011). Before NASA, he worked in forensic seismology. He has a Ph.D. and M.S. in Geophysics from the University of Michigan and A.B. in Earth Sciences from Dartmouth.
