Abstract
A method and system for tracking an object by generating GPS coordinates for the object and a bearing associated with a movement of the object. The GPS coordinates include a latitude, a longitude, and an altitude, which are processed. The GPS coordinates can be processed to correlate the altitude of the object with an identifier that identifies a level within a structure. An icon representing the object then can be accurately located in a first view of a three dimensional model. An indicator can be associated with the icon to indicate the object's level, a bearing of the object, and/or the object's GPS coordinates. The object's GPS coordinates can be compared with a second object location to determine dispatch instructions. The object can be a person, a vehicle, watercraft or an aircraft.
