This document discusses a Group Mobile SLAM project. The project aims to create a real-time 3D map using cameras on first responders' devices that indicates building structures and responder locations. This would allow commanders to monitor a situation as it unfolds. Examples show how police could map a bank robbery scene from outside and how SWAT could clear rooms floor-by-floor while monitoring the indoor map. The project is intended to provide situational awareness for responders in unforeseen situations and could expand to other markets. It leverages existing Motorola camera and networking technologies.
