CZ1061.The horizontal coordinates were established by GPS observations
CZ1061.and adjusted by the National Geodetic Survey in September 1992.
CZ1061
CZ1061.The orthometric height was determined by differential leveling
CZ1061.and adjusted by the National Geodetic Survey in November 1993.
CZ1061.WARNING-GPS observations at this control monument resulted in a GPS
CZ1061.derived orthometric height which differed from the leveled height by
CZ1061.more than one decimeter (0.1 meter).
CZ1061
CZ1061.The X, Y, and Z were computed from the position and the ellipsoidal ht.
CZ1061
CZ1061.The Laplace correction was computed from DEFLEC99 derived deflections.
CZ1061
CZ1061.The ellipsoidal height was determined by GPS observations
CZ1061.and is referenced to NAD 83.
CZ1061
CZ1061.The geoid height was determined by GEOID99.
CZ1061
CZ1061.The dynamic height is computed by dividing the NAVD 88
CZ1061.geopotential number by the normal gravity value computed on the
CZ1061.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
CZ1061.degrees latitude (G = 980.6199 gals.).
CZ1061
CZ1061.The modeled gravity was interpolated from observed gravity values.
