DX3525
DX3525.The horizontal coordinates were scaled from a topographic map and have
DX3525.an estimated accuracy of +/- 6 seconds.
DX3525
DX3525.The orthometric height was determined by differential leveling
DX3525.and adjusted by the National Geodetic Survey in February 1993.
DX3525.* This is a READJUSTED BENCH MARK height.  Code A indicates a
DX3525.distribution rate of 0.0 thru 1.0 mm/km.
DX3525.The height was derived from older observations constrained to new
DX3525.heights in a crustal motion area.  The height is approximate in
DX3525.relation to other heights in its vicinity.
DX3525
DX3525.The geoid height was determined by GEOID99.
DX3525
DX3525.The dynamic height is computed by dividing the NAVD 88
DX3525.geopotential number by the normal gravity value computed on the
DX3525.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
DX3525.degrees latitude (G = 980.6199 gals.).
DX3525
DX3525.The modeled gravity was interpolated from observed gravity values.
