AB2059.The North Carolina/South Carolina HARNS have been completed but,
AB2059.due to contractual restrictions, coordinates for these stations
AB2059.will NOT be published in the near future. In the interim, the
AB2059.published coordinates in North and South Carolina will not be
AB2059.consistent with the Continuously Operating Reference Stations
AB2059.(CORS). The HARN coordinates for these stations are available
AB2059.upon request. Contact Gary Thompson(919-733-3836), or Lewis
AB2059.Lapine(803-896-7700).
AB2059.
AB2059.In addition, the published North and South Carolina positions
AB2059.(NAD 83 (1986)) are NOT consistent with those determined in
AB2059.adjacent state readjustments. The discontinuity between stations
AB2059.located in North or South Carolina and those in adjacent states
AB2059.which have been adjusted to the HARN may be as much as 5
AB2059.decimeters. This will result in a significant loss of accuracy
AB2059.over lines crossing such state borders.

AB2059.The horizontal coordinates were established by classical geodetic methods
AB2059.and adjusted by the National Geodetic Survey in March 1996.
AB2059
AB2059.The NAVD 88 height was computed by applying the VERTCON shift value to
AB2059.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
AB2059
AB2059.The Laplace correction was computed from DEFLEC99 derived deflections.
AB2059
AB2059.The geoid height was determined by GEOID99.
