Minimap

Im currently working on a game and i was wondering if there was some way to make a minimap. my first thought was doing wome thing with a camera that was way up in the sky that just followed the player around and desplayed it in a game object locked in the top corner of the screen. Not sure if this is effeciant or not just wondering. Thanks

Also there is an other suggestion, example render script might be old but gives you an idea:
