When we released VR-TheWorld, we weren’t sure if the defense M&S community was ready for open streaming terrain - distributed interactive simulation has such a strong dependence on correlation. So making a terrain database that runs in all the systems and meets all the requirements is a big job. Not all systems are capable of on-the-fly terrain creation from terrain servers, like VR-Forces and VR-Vantage.
Lately, we are beginning to see more and more use cases for streaming terrain servers in the early stages of large projects. By hosting the GIS data, the foundational data layers (elevation, features, imagery), on a streaming terrain server, project teams are able to start simulating immediately. They can use the terrain agile VR-Forces to plan and execute scenarios months before the terrain databases are even built. And because VR-Forces and VR-Vantage are terrain agile, they can switch to using the static terrain databases when they are finally delivered. Customers are finding that some simulation tasks are started and finished on the open streaming terrain without the need for a static database build.
