      Global vs. local ellipsoid. ... Because of satellite gravity missions, it is currently possible to determine the orthometric height with centimeter level accuracy. It is foreseeable that a global vertical datum may become ubiquitous in the next 10-15 years. If all published maps are also using this global vertical datum by that time, heights ...
