You could create a real time “map” that instead utilizes a camera and view target positioned over the player way above the map at a fixed position which would allow you to fire a line trace into the landscape from the above camera view giving you real time coordinates of the landscape. There is a little more to it, but this would definitely work. You could also place a marker above the player that would make them more visible in the view target. Matt Aspland on YouTube has got some awesome videos on stuff like this.
