MetaVR Africa Terrain
MetaVR™ has built 2,750 geocells of 3D terrain covering the continent of Africa, in its round-earth geocentric Metadesic™ format.
This terrain was built from 15 meter-per-pixel (mpp) NaturalVue imagery and 90 mpp void-filled SRTM (Shuttle Radar Topography Mission) and DTED1 elevation data. In addition, the 3D terrain includes 0.60 mpp high-resolution natural color insets of many African capital cities and others cities of interest. Terrain elevation information was based on 3-arcsecond STRM and DTED level 1 and 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.
Included in this dataset is the high-resolution 3D terrain of the southern Somalia port city of Kismayo, which is populated with hundreds of geographically specific culture models built
This Africa 3D terrain dataset can 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.
The following symbolic representation shows the geographic coverage of the terrain tiles of Africa. 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 are the high-resolution insets.
As additional source data becomes available, MetaVR will continue to build 3D terrain for additional areas to add to its 3D terrain datasets of the world.
Specifications for MetaVR’s Africa terrain dataset in Metadesic format:
MetaVR's Africa 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 Africa terrain data set 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.)
