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
Input the latitude and longitude of a point on the left map and see its corresponding antipode on the right map.
OR, search by place name...
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.

The only antipodal in the USA is the north of Austral French Territory.

Hi Fred, it is displayed below the map but will only start to appear once you zoom in by at least one level. Yes, it will take in to account elevations at either side of the tunnel such as hills or mountains.

Where is the tunnel distance shown? And does it consider local elevations?
By Fred on 27th January 2017
Thx for the info, t was nice to know but I was hoping it would be NZ

Kasper, using your format it should be n53.46.030;w74.47.096. Using latitude, longitude it is 53.46,-74.47

Would some email me with the answer to this question What is the antipode to the following coordinates starting at s53.46.030;e74.47.096 from there to here in North America n_? w_? I just can't figure it out email to: ka*******ail.com

is there a way to draw country boarders on map 2?

Very cool!! I like that you can tunnel straight through and also see the exact other side of the earth while keeping the same longitude.

No, if you dig from Tokyo, you get close-ish but still in the ocean
By Free Map Tools on 22nd August 2016
So Tokyo, Japan ISN'T antipodal to Rio, Brasil...

When zoom in and out from mouse in the map, the position in the other map isn't reflected
