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:
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.
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.
Below are specifications for MetaVR’s CONUS++ terrain dataset in round-earth Metadesic format (MDS).
The following symbolic representation shows the geographic coverage of this 3D dataset’s terrain tiles of all of North America. This 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.
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.
The CONUS terrain contains two AOIs that were built with 2 cm per-pixel resolution imagery collected by MetaVR's remotely piloted aircraft: Prospect Square area at the Yuma Proving Ground, AZ, and two target ranges at the Fallon Range Training Complex, Naval Strike and Air Warfare Center (NSAWC) at Naval Air Station (NAS) Fallon, NV.
MetaVR’s CONUS++ 3D terrain is delivered on a set of six external hard drives that include geospecific terrain constructed from natural color imagery ranging from 0.24 to 1 mpp resolution. Each drive also includes 4 mpp resolution tiles derived from the 1 mpp terrain for customers who need a more compact version of the terrain. The hard drives are organized by region as shown in the following table. Click the thumbnail image of a region to view an enlarged image:
The terrain is provided in MetaVR's round-earth terrain format and will only run with a valid VRSG version 6 software license with valid software maintenance through June 30, 2016. MetaVR’s CONUS++ 3D terrain in Metadesic format 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. For US-domestic use only, not available for export.
The CONUS++ 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 CONUS++ terrain directly from MetaVR. To order a region of CONUS++ terrain, specify the line item on the order form and then provide the name of the region (as described in the table above).
