MetaVR 3D Terrain Products
MetaVR has built several terrain databases over time that meet the needs of our customers who require detailed 3D environments for their simulation.
We create these terrain products using a combination of our commercial tools and new software tools that are under internal development. Each project gives us the opportunity to advance our technology such that our internal tools can evolve into commercial products and our existing products are enhanced.
Terrain source data
We build 3D terrain from a broad range of GIS source data: terrain imagery, digital elevation, and cultural features. At times we may be able to obtain imagery at a higher resolution than what you currently have.
Recently, MetaVR has established a low-cost process for collecting imagery of an area of interest with a small UAV, MetaVRC, and using that imagery in building geospecific 3D terrain with 2-3 cm per-pixel resolution imagery for real-time simulation.
With source imagery, elevation and vector data, we build terrain with MetaVR Terrain Tools for Esri ArcGIS.
Working from overhead imagery and ground-level photographs and the features on the base imagery, we can determine the footprints of cultural features and either use models from our model libraries or create geospecific models of particular structures of interest from photographs provided by the customer or in the public domain.
Culture models are added to the terrain in a variety of ways. Generally, most are placed on the compiled terrain with VRSG Scenario Editor. Some culture, such as airport runway models and large forests of tree models, can be compiled into the terrain in Terrain Tools. Areas of dense urban models can be generated in and output from Esri CityEngine and placed on the compiled terrain.
ORDERING NEW 3D terrain OF AN AREA OF INTEREST
If your site is interested in having MetaVR build a 3D terrain product of an area of interest (AOI) in our round-earth Metadesic™ terrain tile format, provide us with a specification. You can supply your own AOI source data for a custom terrain build. Using this data, we can provide a quote for your terrain product.
The quote for the AOI terrain project contains no labor-based costs. Upon your acceptance of the quote, we will proceed to build the AOI 3D terrain. Payment is required upon acceptance of the terrain product.
Upon a customer's acceptance of the 3D terrain product, MetaVR retains right to redistribute the terrain it has built, free of charge to all US Government agencies and contractors (for official use only). The compiled Metadesic terrain tiles will be distributed with MetaVR VRSG software, as agreed by both parties and provided by the quotation terms and conditions.
Requirements for customer-supplied source imagery
If your site already has source imagery data you want us to use for 3D terrain construction, the data must be provided as follows:
Aerial imagery collected by MetaVR’s remotely piloted portable aircraft
Aerial imagery collected by the MetaVRC can also be ordered from MetaVR by specifying the area of interest, such as an airfield. You can order raw collected data, orthorectified imagery, or a dataset of terrain tiles built with the imagery in MetaVR’s round-earth terrain format, delivered with a VRSG or MetaVR Terrain Tools software license. Access to the area of interest for aerial photography must be in accordance with FAA regulations. Customers will be responsible for obtaining the necessary authorization and certified access to operate within the particular area of interest for aerial photography. For commercial purposes, a remote controlled aircraft in the national airspace is permitted to fly only in Restricted Airspace, or in airspace that has a certified Certificate of Authorization. Flying an aircraft in either types of airspace requires the prior authorization of the airspace owner(s).
