PG0958.The horizontal coordinates were scaled from a topographic map and have
PG0958.an estimated accuracy of +/- 6 seconds.
PG0958
PG0958.The orthometric height was determined by differential leveling
PG0958.and adjusted by the National Geodetic Survey in June 1991.
PG0958
PG0958.The geoid height was determined by GEOID99.
PG0958
PG0958.The dynamic height is computed by dividing the NAVD 88
PG0958.geopotential number by the normal gravity value computed on the
PG0958.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
PG0958.degrees latitude (g = 980.6199 gals.).
PG0958
PG0958.The modeled gravity was interpolated from observed gravity values.
