Fun Google Maps tool you're really going to "dig"!
Sunday, August 28, 2005
Remember when you'd dig a hole in your backyard or at the beach as a kid, and you'd hear friends, parents or a passerby say to you: "If you keep digging, you're going to reach China!" Well, Luis Felipe Cipriani of Brazil is going to help you find out if they were right. He's created the "If I dig a very deep hole, where I go to stop?".... Google Maps tool. :) This will help you determine where, if you were to dig a hole straight to other side of the earth, you would end up!
Luckily for me when I was younger, I stopped digging that hole before letting all the waters of the south pacific gush into my backyard sandbox. That would have been bad. ;)
Does anyone reach China? If you, post a comment and let us know!

From North America, it merely flips me to the quivalent south of te equator.
similar problem. started in texas, ended up in the south pacific. hardly the other side of the planet.
Hi folks,
See the code below that calculates the antipodal point, I believe that is correct:
y is hole end latitude.
x is hole end longitude.
superPoint is the begin of the hole
var y = -1 * superPoint.y;
if (superPoint.x < 0) {
var x = Math.abs(superPoint.x);
x = 180 - x;
} else {
var x = superPoint.x;
x = 180 - x;
x = -1 * x;
}
But, like I said, I´m nbot responsible by the holes that are been made. :-)
Feluardo, good job! kkkk
Here's the updated code that works for me from my house I end up somewhere off the southern coast of Australia.
javascript:function otherSide() { map.closeInfoWindow(); var y = -1 * superPoint.y; var x = superPoint.x; if (superPoint.x < 0) { x = Math.abs(x); x = 180 - x; } else { x = 180 - x; x = -1 * x; } ; var newPoint = new GPoint(x,y); map.recenterOrPanToLatLng(newPoint); map.zoomTo(15); var marker = map.addOverlay(new GMarker(newPoint)); var html = 'Your hole ends here!'; map.openInfoWindowHtml(newPoint, html); };
