Abstract: Systems and methods for dynamically updating and distributing digital reconnaissance maps for incident response. One example system includes an electronic processor coupled to an electronic communication interface. The processor is configured to receive an incident notification for an incident occurring at an incident scene and to generate a reconnaissance map for the incident scene. The processor is configured to receive a voice communication associated with a first incident responder at the incident scene and determine, for the first incident responder, a location within the incident scene.

Abstract: A communication system and method are provided to conduct waterway searches for the detection and identification of objects and the generation of law enforcement agency alerts and pre-approved external agency notifications. A water body surveillance apparatus, under control of a law enforcement agency, surveys above and below a water surface to detect objects and collect data pertaining to the detected objects. The communication system identifies the detected object and generates an alert to the law enforcement agency identifying the object. A notification is sent to pre-approved external agencies based on object type. The pre-approved external agencies may include other law enforcement agencies different from the law enforcement agency and non-law enforcement agencies, such as pre-approved insurance agencies, and vehicle repossession companies, environmental agencies.
