In the interim, the AB6786.published coordinates in North and South Carolina will not be AB6786.consistent with the Continuously Operating Reference Stations AB6786.(CORS). The HARN coordinates for these stations are available AB6786.upon request. Contact Gary Thompson(919-733-3836), or Lewis AB6786.Lapine(803-896-7700). AB6786. AB6786.In addition, the published North and South Carolina positions AB6786.(NAD 83 (1986)) are NOT consistent with those determined in AB6786.adjacent state readjustments. The discontinuity between stations AB6786.located in North or South Carolina and those in adjacent states AB6786.which have been adjusted to the HARN may be as much as 5 AB6786.decimeters. This will result in a significant loss of accuracy AB6786.over lines crossing such state borders. AB6786 AB6786 AB6786.The horizontal coordinates were established by GPS observations AB6786.and adjusted by the National Geodetic Survey in November 1996. AB6786 AB6786.The orthometric height was determined by differential leveling AB6786.and adjusted by the National Geodetic Survey in April 2001. AB6786.No vertical observational check was made to the station. AB6786 AB6786.The Laplace correction was computed from DEFLEC99 derived deflections. AB6786 AB6786.The geoid height was determined by GEOID99. AB6786 AB6786.The dynamic height is computed by dividing the NAVD 88 AB6786.geopotential number by the normal gravity value computed on the AB6786.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45 AB6786.degrees latitude (g = 980.6199 gals.). AB6786 AB6786.The modeled gravity was interpolated from observed gravity values. AB6786 AB6786; North East Units Scale Converg.
