Researchers at the University of Missouri have developed a prototype app that combines a smartphone’s GPS, compass and imaging capabilities to calculate the exact location of distant objects and track their speed and direction. Using comparative sizes of an object from a picture and a manual size input, the app can use the GPS to give an estimated location. Though, at the time, the app meets limitations physically due to the power of current smart phones.
