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 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.

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.
