MetaVR Asia 3D Terrain
MetaVR™ has built 1,931 geocells of 3D terrain covering portions of Asia in its round-earth geocentric Metadesic™ format. The 25,655,300 km2 virtual terrain includes Afghanistan, Armenia, Azerbaijan, Bahrain, Bangladesh, Cyprus, Georgia, India, Iran, Iraq, Israel, Japan, Jordan, Kazakhstan, Kuwait, Kyrgyzstan, Lebanon, Oman, Pakistan, Palestine, Qatar, Russia (southern area), Saudi Arabia, Syria, Tajikistan, Turkey, Turkmenistan, the United Arab Emirates (UAE), Uzbekistan, and Yemen. This terrain was built from 15 meters-per-pixel (mpp) color LandSat imagery, with 2.5 mpp SPOT satellite imagery of Afghanistan, and 1 mpp black-and-white imagery of Iraq, Kuwait, and Syria and portions of Jordan, Lebanon, and Saudi Arabia color-fused with the 15 mpp base imagery. In addition, MetaVR's Asia 3D terrain includes 0.60 mpp high-resolution natural color insets of areas of interest in many of these countries (see specification below). Terrain elevation information was based on 3-arcsecond DTED level 1 and void-filled SRTM (Shuttle Radar Topography Mission) elevation data, subsampled to achieve a nominal 60 m post spacing.
Residing in a geocentric coordinate system, these MetaVR Metadesic (round-earth) terrain tiles are suitable for real-time visualization in MetaVR’s Virtual Reality Scene Generator (VRSG) in applications such as simulation, and synthetic vision such as glass-cockpit displays, intelligence, surveillance, and reconnaissance (ISR) applications, close-air-support (CAS) exercises, and fixed-wing cockpit simulation.
The Asia 3D terrain dataset can also serve as a baseline to which you can add your own higher-fidelity information, such as high-resolution aerial imagery or LIDAR elevation data, GPS point surveys, or 3D point features (such as buildings, trees, targets, and runway models). With this terrain, you can add culture assets from MetaVR’s extensive model libraries and construct pattern-of-life scenarios using MetaVR’s VRSG Scenario Editor.
If information is provided directly from sensors in the field, such information can also be added to the terrain in real time. Using MetaVR’s Terrain Tools for Esri® ArcGIS®, you can update terrain areas of interest as you obtain additional imagery source data.
As additional source data becomes available, MetaVR will continue to build 3D terrain for additional areas to add to its Asia terrain datasets.
The following symbolic representation shows the geographic coverage of the terrain tiles of Asia. This terrain tile coverage map was generated with MetaVR's Model Viewer. The green areas indicate use of 15 mpp imagery and the red areas indicate the high-resolution imagery.
Although the Asia terrain dataset is comprised of portions of Asia, with MetaVR's Terrain Tools for ArcGIS you could construct a terrain of the entire region, or the entire earth.
Specifications for MetaVR’s Asia terrain dataset in Metadesic format:
MetaVR's Asia 3D terrain dataset in Metadesic (MDS) format is available for purchase to MetaVR customers who are on active Virtual Reality Scene Generator™ (VRSG™) software maintenance and are US Government or NATO agencies or contractors (for official use only). The terrain is provided in MetaVR's round-earth terrain format and will only run with a valid VRSG version 6.0 or greater software license with valid software maintenance through June 30, 2016. For US-domestic use only, not available for export.
The Asia terrain dataset is delivered on an external hard drive. (A nominal fee covers the processing of large quantities of data in the Metadesic format and the hard drive distribution media.)
