3. Goals of This Study
• 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
