DC0894.The horizontal coordinates were scaled from a topographic map and have
DC0894.an estimated accuracy of +/- 6 seconds.
DC0894
DC0894.The orthometric height was determined by differential leveling
DC0894.and adjusted by the National Geodetic Survey in February 1993.
DC0894.* This is a READJUSTED BENCH MARK height.  Code F indicates a
DC0894.distribution rate greater than 8.0 mm/km.
DC0894.The height was derived from older observations constrained to new
DC0894.heights in a crustal motion area.  The height is approximate in
DC0894.relation to other heights in its vicinity.
DC0894
DC0894.The geoid height was determined by GEOID99.
DC0894
DC0894.The dynamic height is computed by dividing the NAVD 88
DC0894.geopotential number by the normal gravity value computed on the
DC0894.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
DC0894.degrees latitude (G = 980.6199 gals.).
DC0894
DC0894.The modeled gravity was interpolated from observed gravity values.
