Control Text

  • The North Carolina/South Carolina HARNS have been completed but, due to contractual restrictions, coordinates for these stations will NOT be published in the near future. In the interim, the published coordinates in North and South Carolina will not be consistent with the Continuously Operating Reference Stations (CORS). The HARN coordinates for these stations are available upon request. Contact Gary Thompson(919-733-3836), or Lewis Lapine(803-896-7700). In addition, the published North and South Carolina positions (NAD 83 (1986)) are NOT consistent with those determined in adjacent state readjustments. The discontinuity between stations located in North or South Carolina and those in adjacent states which have been adjusted to the HARN may be as much as 5 decimeters. This will result in a significant loss of accuracy over lines crossing such state borders.
  • The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in September 1992.
  • The orthometric height was determined by differential leveling and adjusted by the National Geodetic Survey in July 1999. The height was determined by precise leveling from only one NSRS bench mark. This was not adequate "tie leveling" to NSRS and was allowed ONLY to validate the GPS-derived height.
  • The Laplace correction was computed from DEFLEC99 derived deflections.
  • The geoid height was determined by GEOID99.
  • The dynamic height is computed by dividing the NAVD 88 geopotential number by the normal gravity value computed on the Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45 degrees latitude (g = 980.6199 gals.).
  • The modeled gravity was interpolated from observed gravity values.
