The Plowshares project is applying military constructive simulation technology to training for emergency management. The project team has enhanced the U. S. Army's Janus simulation model to support emergency management scenarios that include hurricanes, fires, and chemical spills. The enhanced Janus software, known as TERRA, will be used in a county Emergency Operations Center to provide the stimulus for training events structured as command post exercises. The first phase of the project culminated in a "Proof of Principle Demonstration" that occurred in August 1995. In that demonstration the Emergency Operations Center of Orange County Florida conducted a hurricane response exercise using the TERRA system.
