Actual coords of RelativeLocation

Is there a way to get actual latitude, longitude etc. of RelativeLocation?

At the moment this is not reported via an API. It is however quite easy to calculate it in javascript on your end. For this I can recommend the jscoord library (http://www.jstott.me.uk/jscoord/) that makes it easy to convert between WGS84 (latitude, longitude) and UTM (based on north and east coordinates in meteres).
