Abstract: The present invention is an electronic emergency incident notification system (“EEINS”) which allows subscribers to transmit notification of a nuclear/chemical/biological release to a central server for transmittal to the appropriate governmental agencies. In the preferred embodiment, a subscriber would utilize a user interface device to transmit spatial data and an incident report to the central server, typically using the Internet. The central server would map the spatial data onto a GIS database to determine which agencies require notification, and would then transmit the incident report to the receiving nodes at the appropriate agencies. At the local level, the receiving node may include software to automatically activate the appropriate public warning systems. The EEINS is sufficiently flexible to service both fixed and mobile sites.
