MetaVR has posted a video of a real-time flythrough, of 3D geospecific virtual terrain built with 1 inch per-pixel resolution imagery collected with the company’s remote-controlled aircraft and high-resolution elevation data.
The MetaVRC, MetaVR’s remote-controlled hand-launched aircraft for imagery data collection, is a low profile, lightweight, and portable plane, modified to accommodate autonomous flight. The aircraft takes high-resolution still-frame images that, once orthorectified, can be used to build a realistic geospecific synthetic environment for rendering in MetaVR’s Virtual Reality Scene Generator (VRSG).
The aircraft, built by Swift Radioplanes, is designed to fly at or below 400 feet given the appropriate permissions for airspace usage, at a range up to 20 miles depending on regulations of the area. For a 5 sq km area, approximately 2,500 raw images are taken by the aircraft’s camera at one inch (1″) pixel resolution. The portable aircraft will be on display at I/ITSEC 2014, in MetaVR’s Booth #1249.
For the virtual terrain rendered in VRSG and shown in the video, the raw aerial images collected by the MetaVRC were orthorectified and coupled with National Elevation Dataset (NED) 10 meters-per-pixel elevation data of the photographed region to become source data inputs for MetaVR’s Terrain Tools for Esri ArcGIS for compilation. The resulting geospecific synthetic desert environment was compiled at 1 inch per-pixel resolution, which can be rendered in VRSG at 60 Hz.

MetaVR, founded in 1997, develops commercial PC-based software for the military simulation and training markets, featuring high-speed 3D visualization content and rapid creation of networked virtual worlds using real-world data. MetaVR’s real-time visual systems provide the fidelity of geospecific simulation with game-quality graphics. Users can build (with real-world photographic imagery, elevation data, and feature data) high-fidelity virtual worlds with our terrain generation tools, and render in real time, at 60Hz frame rates, the resulting virtual world with our real-time 3D visualization application, Virtual Reality Scene Generator. MetaVR systems are used for applications such as UAS trainers, manned flight simulators, mission planning and rehearsal, JTAC simulation training, urban operations training, and emergency response management training.
