Ball-In-Space Geo Quiz/Challenge....

Here is the game: Determine your exact GPS coordinates on this ball in space. Then, someone fiqure out how to determine the reciprocal coordinates so that you can find the exact opposite position on this globe. If there is a simple formula for us to use,then it might be fun and rewarding to see just what is directly beneath your current location.

Using Terrasevrer-it may be possible to even post an image link of your digs and also the exact opposing patch of dirt; ...or will it be a spot smack dab in the middle of the drink down under......?

Can anyone do the math?? /ubbthreads/images/graemlins/popcorn.gif Ready? Go

This sounds like fun, never thought about this idea...time to get the map out. /ubbthreads/images/graemlins/smile.gif

I think the math is pretty easy. Just take the N/S coordinate and change N to S or vice versa. For the E/W coordinate, subtract it from 180 and change E to W or W to E.

Maybe we have some CPFer who are opposite from each other.
