JK0485
JK0485.The horizontal coordinates were scaled from a topographic map and have
JK0485.an estimated accuracy of +/- 6 seconds.
JK0485
JK0485.The orthometric height was determined by differential leveling
JK0485.and adjusted by the National Geodetic Survey in June 1991.
JK0485.WARNING-Repeat measurements at this control monument indicate possible
JK0485.vertical movement.
JK0485
JK0485.The geoid height was determined by GEOID99.
JK0485
JK0485.The dynamic height is computed by dividing the NAVD 88
JK0485.geopotential number by the normal gravity value computed on the
JK0485.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
JK0485.degrees latitude (G = 980.6199 gals.).
JK0485
JK0485.The modeled gravity was interpolated from observed gravity values.
