Abstract
 A GIS Framework for Improving the Harbor Security Track: Homeland Security/Homeland Defense Author(s): Prasanna Govindan, Yong Tian, Roger Howlett This paper reports on a research using a GIS prototype to improve harbor security. Three types of systems cited as major tools in preventing terrorist attacks are critically examined here: (1) a spatially coordinated sensor network for security monitoring and emergency response, (2) distributed information management for data compression and knowledge discovery, and (3) discrete simulation of plume evolution by incorporating real-time climate and geophysical data. The monitoring system allows controlling the motion of sensors (e.g., camera) via the Internet by selecting a geospatial location of the target from a GIS map. A central temporal database was used to maintain real-time ship tracking records from different remote areas with data compression. These archived historic data can be used to analyze data to infer possible terrorist actions. Simulation of plume evolution was developed using cellular automata approach to assess the impacts of a disaster in a coastal environment.
