MetaVR Continental US Plus Alaska and Hawaii (CONUS++) 3D Terrain

MetaVR's seamless 3D terrain of Continental US plus Alaska and Hawaii (CONUS++) is constructed with DTED level 1 elevation data and with natural color imagery ranging from 0.025 to 1 meter-per-pixel (mpp) resolution for the CONUS area itself and DTED 0 to DTED 2 elevation data for Alaska and Hawaii with natural color imagery ranging from 0.25 to 2 meter resolution.

Covering an area over 1,900-geocells, the terrain includes high-resolution insets of several areas of interest including military installations and urban areas. Each high-resolution inset contains image data ranging in resolution from 0.025 m to 0.75 m. 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 CONUS++ dataset can also serve as a baseline to which you can add higher-fidelity information to refine the database in a given area of interest. For example, you can add high-resolution aerial imagery or LIDAR elevation data, GPS point surveys, or 3D point features such as buildings, trees, targets, and runway models. You can make these additions as they become available, even in real-time if information is provided directly from sensors in the field. The Metadesic terrain architecture automatically signals any listening runtime visualizations that new data is available to be paged into memory. This update flexibility is:

  • Efficient - conventional simulations applications do not need to recompile entire dataset upon receipt of new data.

  • Scalable - independent assets can be applied to both construction and visualization.

  • Innovative - mission rehearsal and battle damage assessment tasks can now include a 3D visualization component that is sensor-data driven.

MetaVR updates this 3D terrain on an ongoing basis as new source data become available. The CONUS++ 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.

With this terrain, you can add culture assets from MetaVR’s model libraries of over 6,800 models and construct pattern-of-life scenarios using MetaVR’s VRSG Scenario Editor.

You can build higher-resolution terrain tiles with Terrain Tools for Esri ArcGIS with your own source data to refine the terrain for a given area of interest.  You can also request terrain enhancements or higher resolution terrain tiles from MetaVR.

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.

 Areas of interest

The CONUS++ terrain contains several high-resolution areas of interest to our customers, which are built with insets of higher resolution imagery and elevation and geolocated, and often geospecific, cultural features.

Many of these areas are modeled from photographs taken at the actual site. The Albuquerque International Sunport / Kirtland AFB example shown above is one of over 25 CONUS++ airfields built by MetaVR.

Below is one of several MOUT sites that MetaVR has built with substantial 3D content created from publicly available photos and videos.
