Documented History (by the NGS)
|01/01/1984 by NCGS (MONUMENTED)
|DESCRIBED BY NORTH CAROLINA GEODETIC SURVEY 1984
THE STATION IS LOCATED IN SHELBY. ALONG US 74 BYPASS FOR 0.80 KM (0.50 MI) WEST FROM THE NC 18 OVERPASS, OR 0.08 KM (0.05 MI) WEST OF HAMRICK STREET, IN THE MEDIAN. STATION IS LOCATED 8.35 M (27.39 FT) NORTH OF THE CENTERLINE OF US 74 EAST BOUND LANES, 8.17 M (26.80 FT) SOUTH OF THE CENTERLINE OF US 74 WEST BOUND LANES, 10.85 M (35.60 FT) EAST-SOUTHEAST OF A METAL ROAD SIGN, 13.35 M (43.80 FT) SOUTHEAST OF A METAL ROAD SIGN--AND 46.63 M (152.99 FT) WEST-NORTHWEST OF A POWER POLE, 19.60 M (64.30 FT) WEST-SOUTHWEST OF A ROAD SIGN--BOTH WITH REFERENCE TAGS. MARK IS RECESSED 6 INCHES BELOW GROUND AND IS 1 FT (0.3 M) LOWER THAN THE HIGHWAY.

- 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Carolina HARNS have been completed but, due to contractual restrictions, coordinates for these stations will NOT be published in the near future.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- The NAVD 88 height was computed by applying the VERTCON shift value to the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.) The vertical order pertains to the superseded datum.
- The Laplace correction was computed from DEFLEC99 derived deflections.
- The geoid height was determined by GEOID99.
