A method, apparatus and computer software for coding for tracks in a system is presented. At least one track of an object is determined on a detection display map, the track having an icon associated therewith. The icon is supplemented with a shape indicating additional information relating to attributes of the track, the shape providing perceptual visual awareness for an operator of said system. The shape includes an indicator of at least one of direction, velocity, path uncertainty, and a level of urgency of the track of the object.
