Upon report of an emergency incident, a system may dispatch one or more initial entities to respond to the incident and model an initial scene, based on the reported data. The system may further determine the availability of travel data, request available travel data and advise an entity of path feasibility. The system also determines availability of onsite data covering one or more locations associated with the incident and requests available onsite data. This data is used to update the scene model and determine additional necessary dispatches, data gathering, or both. Until additional data is determined to be no longer needed, the processor is configured to continue to: dispatch entities based on the updated scene model; determine the availability of additional onsite desired based on the updated scene model; request the new onsite data; and update the scene model based on any onsite data received responsive to any additional requests.
