JC1174
JC1174.The horizontal coordinates were scaled from a topographic map and have
JC1174.an estimated accuracy of +/- 6 seconds.
JC1174
JC1174.The orthometric height was determined by differential leveling
JC1174.and adjusted by the National Geodetic Survey in June 1991.
JC1174
JC1174.The geoid height was determined by GEOID99.
JC1174
JC1174.The dynamic height is computed by dividing the NAVD 88
JC1174.geopotential number by the normal gravity value computed on the
JC1174.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
JC1174.degrees latitude (g = 980.6199 gals.).
JC1174
JC1174.The modeled gravity was interpolated from observed gravity values.
