Where Do They Walk Upside Down?

I remember in some cartoons the other side of the Earth being presented as people walking upside down.  Typically a character would fall through a hole in the Earth.   For some reason this was often presented as China. As I grew up in New York, I presumed that if I ever fell through a bottomless pit, I would end up further south– maybe Australia or New Zealand.

Turns out I would have ended up in the Indian Ocean: in the same general vicinity of the missing Malaysian Airlines flight.   In fact most of the United State is opposite the Indian Ocean.  The only exception I can find is Hawai'i is opposite Botswana.  Who knew?

This is what I did when home sick on Sunday in October.  I used the Google Maps API, to do reverse Geocoding.  This worked pretty well, I could get the current latitude and longitude, invert and add 180º, and see where I end up.  The maps API made it simple to select spots on the map, and look up addresses at different levels of granularity.  The only problem I found, is that I couldn't reverse-geocode, to oceans or geographic features.  There has to be a location for that data somewhere.  I will have to search.
