MetaVR South America 3D Terrain

MetaVR's seamless 3D terrain of the continent of South America is constructed with 3-arcsecond STRM elevation data and with natural color imagery ranging from  0.60 to 15 meter-per-pixel (mpp) resolution.

Covering an area over 17,814,000 sq km (1,718 geocells), the terrain includes 60 cm high-resolution natural color insets of insets of many South American capital cities and others cities of interest. Built with MetaVR’s Terrain Tools for Esri® ArcGIS®, the round-earth Metadesic™-formatted terrain tiles reside in a geocentric coordinate system.

These tiles are suitable for real-time visualization and simulation applications that use MetaVR Virtual Reality Scene Generator™ (VRSG™), including synthetic vision, glass-cockpit displays, intelligence surveillance, and reconnaissance (ISR) applications, close-air-support (CAS) exercises, and fixed-wing cockpit simulation.

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.

The South America 3D terrain is "Additional Materials" and is provided "as is" as described in our license agreement.  Although MetaVR might modify or enhance the original source imagery, some visual artifacts from the source imagery might remain in the terrain tiles.

 Delivery

MetaVR’s South America 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.

MetaVR’s South America 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.

The South America 3D terrain set is available in its entirety or in regions of interest (as described in the table above). A fee covers processing large quantities of data into Metadesic format and hard drive distribution media.

You can order the South America terrain directly from MetaVR.
