The four which have been specified are: 1.Through the Capitol 2.Through the White House 3.Through the old Naval Observatory 4.Through the new Naval Observatory. Their longitudes may be reported in three ways: 1. relative to the local vertical used by astronomic observations 2. relative to NAD 27 (North American Datum 1927), an ellipsoid of revolution tangent to mean sea level at triangulation station Meade's Ranch, Kansas (not earth-centered); 3. relative to NAD 83, an earth-centered ellipsoid of revolution whose dimensions are chosen to minimize the undulations of the geoid (world-wide mean sea level; to less than 100 m).
