To quote from the site "The SimTable takes sandtable exercise to the next level by making sandtables real. The SimTable is a 3D interactive fire simulator, bringing sandtable exercises to life." Below is a Los Alamos National Lab video demonstrating their use of the SimTable in their Emergency Operations Center.
The movie below demonstrates more of the functionality of SimTable , specifically how one can simulate rainfall and how it flows over the terrain. Or how it can be used to simulate a wildfire spreading and how residents might evacuate from the area.
