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
Options
[Map Height : Small - Medium - Large]
Unlink Zoom between Map 1 and Map 2
Keep on the same latitude
Flip Map 2 Upside Down
Manual Input
Input the latitude and longitude of a point on the left map and see its corresponding antipode on the right map.
Latitude Longitude
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.

Future Developments
Ideas and improvements that are due to be implemented in the future. If you think of any ways of improving this tunnelling tool or spot any bugs, then please get in touch.
- Display Coordinates of cross-hairs on screen
- KML download for each of the two points for use in Google Earth
- If both maps were overlayed with transparency and one map was upside down

I have to put in latitude and longitude. I just want to put in Virginia and have it do the work for me.

Something is wrong with the latitude finding. The map is showing antipodes in the Northern Hemisphere for points in the Northern Hemisphere. Longitude seems to be working correctly, though.
By Michael Seifert on 16th November 2021
This is completely wrong. Points in the northern hemisphere must always yield results in the southern hemisphere, but that is not happening.

To answer the question "At what point on each of the main highways of
Taiwan do they cross the (virtual (antipodal)) Argentina / Paraguay
border?" What we need is an overlay!

Hi, its in decimal DMS, for example the Eiffel tower would be 48.8583 and 2.2944

How do you add latitude and longitude? What format? Please include an example.
By Curious on 24th September 2020
Now it finally works. When I tried it months ago, it was wrong but now it's correct.
