MetaVR Asia 3D Terrain

MetaVR™ has built 6,411 geocells of 3D terrain of the continent of Asia and the Middle East in its round-earth geocentric Metadesic™ format. The 44,579,000 sq km virtual terrain was built with MetaVR’s Terrain Tools for Esri® ArcGIS® from 15 meters-per-pixel (mpp) color NaturalVue 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 many capital cities and other areas of interest in many of these countries (listed in 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.

Included in this dataset is the high-resolution model of an Afghan village in Kabul province, which is based on the village of Khairabad and is populated with over 650 building models.

Also included with the high-resolution (60 cm) city of Dubai with over 6,000 realistic 3D building models, which were created with Esri CityEngine. The models were extruded and textured from Open Street Map (OSM) data.

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.

 Delivery

MetaVR’s Asia 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 Asia 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 the Asia 3D terrain directly from MetaVR.
