KV0520
KV0520.The horizontal coordinates were scaled from a topographic map and have
KV0520.an estimated accuracy of +/- 6 seconds.
KV0520
KV0520.The orthometric height was determined by differential leveling
KV0520.and adjusted by the National Geodetic Survey in June 1991.
KV0520
KV0520.The geoid height was determined by GEOID99.
KV0520
KV0520.The dynamic height is computed by dividing the NAVD 88
KV0520.geopotential number by the normal gravity value computed on the
KV0520.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
KV0520.degrees latitude (g = 980.6199 gals.).
KV0520
KV0520.The modeled gravity was interpolated from observed gravity values.
