Makai Ocean Engineering has developed 3D/4D visualization software called Voyager that can handle large scientific datasets with GIS integration. It allows users to visualize, analyze and fuse multi-dimensional earth and ocean data, including volumetric grids, terrain, imagery, LIDAR and time-varying variables. The software is optimized for speed and large data handling to enable interactive exploration and common operational picture for disaster response, science, engineering and military applications. Makai is now commercializing the software.

- 4. Product Goals Global geo-referenced Dynamic geo-referenced GIS (vector & raster data) Imagery & Terrain/Bathy Iso-surfaces & Volumes & KML Objects + + Multiple layers / fuse and analyze data Multi-variable data fusion & analysis > 150 different formats Common Operating Picture: advanced scientific visualization, GIS, and graphing, into common view. Global Geo-referenced View Speed: Operate on standard PC at interactive rates; Platform Independent: Windows, Linux, OSX; Large Data: Handle large volumetric grids (> 5123) with multiple variables and with potentially unlimited time-steps; Web-Enabled: Web-app for remote visualization. Images + Terrain + Volume + Flow + Time
- 5. What’s the problem? First off: what is “4D”? 3D volumetric data: x, y, z, with some attribute (e.g., temperature, wind speed, etc.) 2D: Each pixel is a data sample 4D = 3D + time Displaying 4D data can be challenging: Data and scene management Georeferencing Speed Status Quo? Volumetric data not handled adequately by: Leading interactive 3D imagery/terrain software (Google Earth) Leading GIS software (… you know who)
- 6. Who Cares? Anyone dealing with complex 3D & GIS data. This includes: Disaster Management Ocean / Earth / Atmosphere Science 2D: Each pixel is a data sample Geology / Mining / Oil & Gas Environmental / Hydro Engineers Military - Tactical Displays for Situational Awareness GIS Professionals with complicated 3D problems … hopefully you!
- 7. Technical Challenge Understanding large 4D data sets Traditionally visualized using single 2D layers Images & terrain are associated with pixels (X, Y → elevation/color) – i.e., 2D images 4D data are associated with voxels (X, Y, Z, time → multiple variables) 2D VIEWS 3D VIEWS
- 8. Render, faster, better: Interactivity is achieved for very large data using: Data tiling for time-varying 2D and 3D data (similar to what GE does for terrain); Efficient compression algorithms; Accelerated GPU rendering; and, Multi-threading capabilities of modern processors.

- 19. Disaster Management Processes, Integrates and Visualizes Real-time Data Sensors Public Data Streamed GIS • Legacy and real-time sensor data: (land, air, underwater) in space & time in common view. Situational Feedback • Increase surveillance efficiency: reduce op 3D manpower – consolidate 2D flat views in a true 3D/4D Awareness Viewer visual environment. For Field Units • Data fusion from multi-sources: reducing decision-making and response time. • Open architecture: can be expanded and customized easily. • Simulation: threat situations for training of emergency responders
- 20. Tactical Display: Integration with P3 Anti-submarine warfare: In summer/fall 2010 Makai worked with Lockheed to integrate 4D Visualization technology in the acoustic subsystem for the P3-C Orion aircraft
- 21. Integrated acoustic propagation algorithms w/ 4D environmental data. Application for ocean, but could easily be modified for land sound abatement analysis.
