Tunnel to the Other Side of the Earth
Have you ever wondered which part of the other side of the earth is directly below you? Find out using this map tunnelling tool.
Map Tunnelling Tool
Unlink Zoom between Map 1 and Map 2
Keep on the same latitude
Flip Map 2 Upside Down
Input the latitude and longitude of a point on the left map and see its corresponding antipode on the right map.
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.
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.

Now it finally works. When I tried it months ago, it was wrong but now it's correct.

Fascinating tool. It would be very nice to see the results shown on a globe

The tool does not work for northern europe. A point in Norway pairs with a point in far north-east Russia (Chukotka). this is not correct as both points are in the northern hemisphere.
