The highest spot on earth is Mount Everest(that is the point furthest from the assumed "geoid" - the mean sea level)The point furthest from the geometric center of the Earth is the peak of the volcano Chimborazo (in Ecuador and part of the Andes). Although just 6,267 m above sea level (Everest is 8,848 m) the flattening of the earth at higher latitudes makes the mountains near the equator much further from the center of the planet.
