In the interim, the EA2796.published coordinates in North and South Carolina will not be EA2796.consistent with the Continuously Operating Reference Stations EA2796.(CORS). The HARN coordinates for these stations are available EA2796.upon request. Contact Gary Thompson(919-733-3836), or Lewis EA2796.Lapine(803-896-7700). EA2796. EA2796.In addition, the published North and South Carolina positions EA2796.(NAD 83 (1986)) are NOT consistent with those determined in EA2796.adjacent state readjustments. The discontinuity between stations EA2796.located in North or South Carolina and those in adjacent states EA2796.which have been adjusted to the HARN may be as much as 5 EA2796.decimeters. This will result in a significant loss of accuracy EA2796.over lines crossing such state borders. EA2796 EA2796 EA2796.The horizontal coordinates were established by classical geodetic methods EA2796.and adjusted by the National Geodetic Survey in July 1986.
