KV1425
KV1425.The horizontal coordinates were scaled from a topographic map and have
KV1425.an estimated accuracy of +/- 6 seconds.
KV1425
KV1425.The orthometric height was determined by differential leveling
KV1425.and adjusted by the National Geodetic Survey in June 1991.
KV1425
KV1425.The geoid height was determined by GEOID99.
KV1425
KV1425.The dynamic height is computed by dividing the NAVD 88
KV1425.geopotential number by the normal gravity value computed on the
KV1425.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
KV1425.degrees latitude (g = 980.6199 gals.).
KV1425
KV1425.The modeled gravity was interpolated from observed gravity values.
KV1425.The observed gravity was obtained from relative gravimeter ties
KV1425.to the IGSN71 gravity network.
