An emergency response system (ERS) configured to acquire target terminal location data and emergency responder terminal location data, determine a horizontal distance measure between the emergency responder terminal and each of the plurality of target terminals, determine a vertical distance measure between the emergency responder terminal and each of the plurality of target terminals, engage a camera component of the emergency responder terminal to capture images of at least a portion of the surrounding real-world scene, providing such images for display on the touchscreen display of the emergency responder terminal, and/or providing a target terminal display object for display on the touchscreen of the emergency responder terminal such that, when an image provided for display spans a region of the real-world scene within which a target terminal is located, the target terminal display object dynamically overlays a segment of the image associated with the acquired target terminal location data.
