advancements in visualization of remotely sensed 3d data
DESCRIPTION
2013* GEOINT Lightning Talk presentation given by Matt Bethel, Director of Technology for Merrick & Company's Geospatial Solutions team. Presentation given on Monday, April 14, 2014 at the Tampa Marriott Waterside Hotel in Tampa, Florida.TRANSCRIPT
Matt Bethel Advancements In Visualization Of
Remotely Sensed 3D Data
Agenda
• Review of 3D point data sources
• Historical methods of managing this data
• Introduction to a revolutionary and disruptive
technology for accessing and rendering unlimited
amounts of 3D data
3D Point Data Sources
• ATE
• SAR / IFSAR
• LiDAR / LADAR
– Airborne
– Mobile
– Terrestrial
– Underwater
– Autonomously collected
• Newer processes
– SFM (computer vision)
– SGM (photogrammetry)

Historical Point Data Handling Methods
• Rasterizing elevation data – Works well in open land
cover
– Cannot represent multiple height features
– Does not work with FOPEN data
• Loading points into memory (RAM)
• Point decimation
• Streaming from disc
• Vectorizing features

Advanced Spatial Indexing Solution • Real time 3D data rendering at full resolution and detail
• Massive data (density, extent, or both) is now accessible and usable
• Compressed data size
• Data loads in 1 second no matter the size
• Unlimited amount of data to manage, load, display, etc.
• Low computer resource requirements
• Preserves true 3D data, not derivative products
• Capable of streaming 3D data across secured network or internet
• Cost savings - make use of data that already exists
• Centralized data storage
• Version control
• Opportunity for 3D imagery and 3D models
