Goals of This Study
September 28-30, 2010 HDF and HDF-EOS Workshop XIV 3
• Explore a unified data model for information retrieval, visualization, and analysis
• Identify the role that HDF5 can play as a data management platform for Battlefield operations
• Demonstrate the use of web-based tools in combination with HDF5 to organize and work with a wide range of operational data
