Identifying Emergency Meeting Locations for NGA Employees in Metropolitan St. Louis

Rochelle D. Lefarth, University of Redlands


The Mission Assurance Office of the National Geospatial-Intelligence Agency (NGA) required the identification of alternate meeting locations to be used in the event a disaster destroys, damages, or denies access to the NGA offices in the metropolitan St. Louis area. The locations of these meeting sites would be based on where employee residences are clustered.

Hospitals, fire stations and police stations were buffered to avoid conflict with emergency operations. Potential meeting sites were identified. Because this project was being completed outside of an NGA facility, fictitious employee residences had to be created to avoid Privacy Act violations. These fictitious employees were grouped according to NGA criteria and by geographical proximity, and then assigned to potential meeting sites.

As a final step, maps were created in two formats: one large scale format for employee distribution; and the other, a small scale format for official NGA use only indicating the locations of all suggested meeting sites.

Although allowances were necessary because the research was not performed within an NGA facility, and therefore the researcher did not have access to sensitive data, the basis of a system that will be able to identify alternate meeting locations based on where residences are clustered was successfully created.
