A way to use the entire world as a map in your game

Hi Derek, this looks interesting, curious what/how you’ve done this? I am trying to start a location based treasure hunt style mobile game but finding it impossible to find any info anywhere about how to use mobile gps data or geolocation data inside Unreal as part of a mobile experience. Apparently there is a node in Blueprint now but I can’t find any info on it anywhere? Anyt thoughts that might help please?
