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 0.60 mpp high-resolution natural color insets of many South American capital cities and other cities of interest. Built with MetaVR’s Terrain Tools for Esri® ArcGIS®, the round-earth Metadesic-formatted terrain tiles are for use in MetaVR Virtual Reality Scene Generator (VRSG).
These tiles, which reside in a geocentric coordinate system. are suitable for real-time visualization and simulation applications 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.
Geographic coverage by imagery resolution
The following symbolic representation shows the geographic coverage of this 3D dataset’s terrain tiles of all of South America. This terrain tile coverage map was generated with MetaVR’s Model Viewer. The areas in green indicate 15 mpp imagery, the orange-brown areas indicate 1 mpp resolution imagery, and the bright red areas indicate imagery resolution of less than 1 mpp.
