Integrated emergency event detection and mapping using individualized device location registrations

A software platform includes emergency event processing functionality for detecting and mapping emergency event occurrences. The emergency event processing includes device location registration functionality for allowing operators of the software platform to register locations of their devices. Information associated with the operator-entered location information is stored alongside network device information. When an emergency call is placed by a device registered with the software platform, the software platform identifies network device information for the device placing the emergency call and searches records generated based on the operator-indicated device locations. A location determined thereby is then signaled to a public safety answering point. This automated signaling can improve an emergency response by directing dispatched responders to a specific location verified by the operator of the device, rather than an assumed location specified by an administrator which may not actually be accurate.
