OQ0045.The horizontal coordinates were established by classical geodetic methods
OQ0045.and adjusted by the National Geodetic Survey in January 1998.
OQ0045.No horizontal observational check was made to the station.
OQ0045
OQ0045.The orthometric height was determined by differential leveling
OQ0045.and adjusted by the National Geodetic Survey in September 1993.
OQ0045
OQ0045.The X, Y, and Z were computed from the position and the ellipsoidal ht.
OQ0045
OQ0045.The Laplace correction was computed from DEFLEC99 derived deflections.
OQ0045
OQ0045.The ellipsoidal height was determined by GPS observations
OQ0045.and is referenced to NAD 83.
OQ0045
OQ0045.The geoid height was determined by GEOID99.
OQ0045
OQ0045.The dynamic height is computed by dividing the NAVD 88
OQ0045.geopotential number by the normal gravity value computed on the
OQ0045.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
OQ0045.degrees latitude (g = 980.6199 gals.).
OQ0045
OQ0045.The modeled gravity was interpolated from observed gravity values.
