MetaVR Asia 3D Terrain

MetaVR used its Metadesic Compiler to build 455-geocell 3D terrain of subsets of Asia. The current 4,550,000 km² area includes terrain tiles built from 1-meter black-and-white imagery color fused with 15-meter color LandSat imagery of Iraq and Kuwait (approximately a 70-geocell area) and 60 cm high-resolution natural color insets of Baghdad, Basra, and Kirkuk. The terrain also includes tiles built from 15-meter LandSat imagery of Afghanistan, Pakistan, northwest portion of India, Uzbekistan, Turkmenistan, Tajikistan, and the eastern section of Iran. Elevation for the terrain is 60 meters-per-post.

The terrain tiles reside in a geocentric coordinate system and are suitable for real-time visualization, simulation, and synthetic vision such as glass-cockpit displays, intelligence, surveillance, and reconnaissance (ISR) applications and fixed-wing cockpit simulation.

This dataset can also serve as a baseline to which you can add your own higher-fidelity information. such as high-resolution aerial imagery or LIDAR elevation data, GPS point surveys, or 3D point features (such as buildings, trees, targets, and runway models). If information is provided directly from sensors in the field, this information can be added to the terrain in real-time. Using MetaVR's Metadesic terrain compiler, you can update terrain areas of interest as you obtain additional imagery source data.

As additional source data becomes available, MetaVR will continue to build additional terrain of the Asia continent.

The following symbolic representation shows the geographic coverage of this this 3D dataset's terrain tile. This coverage map was generated using MetaVR's Model Viewer.

Although this terrain dataset is comprised of parts of Central and Southern Asia and the Middle East, with the Metadesic Compiler you could construct a terrain of the entire region, or the entire earth.

The Metadesic (MDS) format dataset requires VRSG version 5 or greater.
