ArcGIS Exercise: Chemical Terrorism Risk & Evacuation Assessment


Approximately 75 minutes

Course Description:

The course "Chemical Terrorism Risk and Evacuation Assessment" is designed to give you a basic understanding of how to apply ArcGIS geographic information system tools to map and analyze multiple hazard threat zones and estimate at-risk households and evacuation populations as a result of a chemical terrorism scenario involving potential bomb blasts and subsequent releases of chlorine gas. It is an exercise in tutorial format, with step-by-step instructions utilizing data for the island of O`ahu.

The exercise requires access to ArcGIS ArcView version 9.1, 9.2, or later, and the Spatial Analyst extension. Evaluation copies of the software are available at the following URL:
