EV1025
EV1025.The horizontal coordinates were scaled from a topographic map and have
EV1025.an estimated accuracy of +/- 6 seconds.
EV1025
EV1025.The orthometric height was determined by differential leveling
EV1025.and adjusted by the National Geodetic Survey in May 1994.
EV1025
EV1025.The geoid height was determined by GEOID99.
EV1025
EV1025.The dynamic height is computed by dividing the NAVD 88
EV1025.geopotential number by the normal gravity value computed on the
EV1025.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
EV1025.degrees latitude (G = 980.6199 gals.).
EV1025
EV1025.The modeled gravity was interpolated from observed gravity values.
