Put the origin of the world in the corner of tile 0,0.

Browse Source 
Negative x/z will be put into negative tiles, so you can easily determine
the tile location by dividing the x or z by 16*tileSize. This means the same area of the world
will always end up in the same tile, independent of how much of the world is generated.
