Geolocation is closely related to positioning but can be distinguished from it by a greater emphasis on determining a meaningful location (e.g. a street address) rather than just a set of geographic coordinates. Specifically this involves the use of advanced RF location systems utilising, for example, Time Difference Of Arrival (TDOA) where greater specificity of location is possible. TDOA systems often utilise mapping displays or other graphical information system. This is in contrast to more traditional radiolocation technologies, for example Direction Finding where a line of bearing to a transmitter is achieved and not the specific location.
