How do I locate?

Postby hhomebrewer » Sat Feb 27, 2010 7:13 pm

How do I locate the point on the Earth that is diametrically opposed to where I am? I am in the Northern Hemisphere, in Nevada. I want to see the place on the other side of the world, going through the center of the Earth. I am going to assume it's out in the ocean, somewhere. Assume my location to be in Reno at 39 degrees, 32.236 minutes North by 119 degrees, 47.277 minutes West. What is the math I use to figure out where the point is that I seek? I know it has something to do with 180 degrees, but to what do I add or subtract that value?

You can use this tool:

Just move the crosshairs on the left to your location and it shows the antipode on the map on the right.

Ironically enough, the only place in the US that doesn't tunnel into water is Hawaii.

Where does that hole go to if you are in China? To China? Or what. :-?

It's as easy as changing North to South (or the other way round) and take the norm from your longitude [ch955] minus 180

1296.77 miles southeast of the very lowest point on Madagascar, on a 141.51 degree heading. I have a screenshot, but it's too big to post...
