How to use the Map Tunnelling Tool

Drag map 1 or 2 by clicking and holding the map as you move it. When you let go and finish dragging the map the other map will then show you where about's on the earth the far end of the imaginary tunnel will be. In effect it will show you what is at the other side of the earth.

To make things easier, you can also zoom the map in and out.

You can adjust the height of the map by using the small, medium and large buttons.

You can also change the map view using the Map, Satellite and Hybrid buttons. This works independently for each map.

About

This is a Antipodes Map. An antipode of a point on the earth is the region on the Earth's surface which is diametrically opposite to that point. The two points which are antipodal to one another are considered to be connected by a straight line or tunnel through the centre of the Earth.
