MZ0897  VERT ORDER  -  FIRST     CLASS I
MZ0897
MZ0897.The horizontal coordinates were scaled from a topographic map and have
MZ0897.an estimated accuracy of +/- 6 seconds.
MZ0897
MZ0897.The orthometric height was determined by differential leveling
MZ0897.and adjusted by the National Geodetic Survey in June 1991.
MZ0897.WARNING-Repeat measurements at this control monument indicate possible
MZ0897.vertical movement.
MZ0897
MZ0897.The geoid height was determined by GEOID99.
MZ0897
MZ0897.The dynamic height is computed by dividing the NAVD 88
MZ0897.geopotential number by the normal gravity value computed on the
MZ0897.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
MZ0897.degrees latitude (g = 980.6199 gals.).
MZ0897
MZ0897.The modeled gravity was interpolated from observed gravity values.
