Modern information systems that are designed to plan for and respond to Chemical, Biological, and Radiological (CBR) attacks are now attempting to include airborne contaminant plume models in their application package. These plume models are a necessary component for the emergency personnel responding to an actual event and to those charged with developing an effective response plan in advance. The capabilities to create a variety of CBR-event scenarios quickly, to determine possible contaminant agent release locations from reports and sensor data, and to predict the path of a plume before it gets there, are functions that many involved in the military and homeland security will find beneficial. For this reason CT-Analyst's ability to generate accurate, time-dependant plumes that can be rendered much faster than real-time and can be adjusted and modified on the screen, is an incredible asset to developers of these civil defense systems. The value of the fast, accurate CT-Analyst computer models for complex urban terrain is greatly increased when the capabilities can be imported into platforms users and developers are already taking advantage of. CT-Analyst's strengths can now be accessed through other applications, GIS tools, and development environments. This process will be described to show how this is possible, to which systems it can be applied, and what benefits can result.
