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 with MetaVR’s Terrain Tools for Esri® ArcGIS® 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.

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
from ground-level photographs taken on the streets of Kismayo. In addition to these geolocated and photo-realistic models of buildings and other structures, several hundred other buildings were modeled by matching the structural footprints visible in the imagery as geotypical models with culturally and architecturally accurate details.

 Delivery

MetaVR’s Africa 3D terrain is delivered on an external hard drive. The terrain is provided in MetaVR's round-earth Metadesic terrain format and will only run with a valid VRSG version 6 software license with valid software maintenance through March 1, 2017. A fee covers processing large quantities of data into Metadesic format and hard drive distribution media.

MetaVR’s Africa 3D terrain is available for purchase to MetaVR customers who are US Government agencies or contractors (for official use only). Customers can duplicate the data at their discretion as long as the data is used in conjunction with a valid VRSG license.

You can order this 3D terrain dataset directly from MetaVR.
