CT-Analyst GIS Data Processing Guidance Document

Abstract

CT-Analyst is a hazardous plume modeling application developed by the Naval Research Laboratory in Washington, DC. CT-Analyst adapts to limited known source information by pre-calculating from modeling runs done on a variety of modeling conditions and differing prevailing wind directions and velocities. This pre-calculation is done by way of highly complex, highly-accurate Computational Fluid Dynamic (CFD) computer codes run on high-performance computer systems, which produce usable Nomograf tables. While these Nomograf tables serve as the output from these CFD codes, the input provided are essentially 3-dimensional models of the region or area-of-interest that is intended to be modeled, like a city, military base, industrial plant, etc., and fully describe the ground terrain, buildings, trees, and water. The models require specific input datasets, whose construction and development should be described in detail.
