DX3486.The horizontal coordinates were scaled from a topographic map and have
DX3486.an estimated accuracy of +/- 6 seconds.
DX3486
DX3486.The orthometric height was determined by differential leveling
DX3486.and adjusted by the National Geodetic Survey in February 1993.
DX3486.* This is a READJUSTED BENCH MARK height.  Code A indicates a
DX3486.distribution rate of 0.0 thru 1.0 mm/km.
DX3486.The height was derived from older observations constrained to new
DX3486.heights in a crustal motion area.  The height is approximate in
DX3486.relation to other heights in its vicinity.
DX3486
DX3486.The geoid height was determined by GEOID99.
DX3486
DX3486.The dynamic height is computed by dividing the NAVD 88
DX3486.geopotential number by the normal gravity value computed on the
DX3486.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
DX3486.degrees latitude (G = 980.6199 gals.).
DX3486
DX3486.The modeled gravity was interpolated from observed gravity values.
