Documented History (by the NGS)

01/01/1934 by CGS (MONUMENTED)
01/01/1952 by NGS (GOOD)
DESCRIBED BY NATIONAL GEODETIC SURVEY 1952 10 MI N FROM FLORENCE. 10.0 MILES NORTH ALONG STATE HIGHWAY 67 FROM THE POST OFFICE AT FLORENCE, 15 FEET EAST OF THE CENTER LINE OF THE HIGHWAY, SET IN THE TOP OF THE NORTH END OF THE NORTHEAST WINGWALL OF A CONCRETE BRIDGE OVER EAST EIGHT MILE CREEK.

Control Text

  • The horizontal coordinates were scaled from a topographic map and have an estimated accuracy of +/- 6 seconds.
  • The orthometric height was determined by differential leveling and adjusted by the National Geodetic Survey in June 1991.
  • 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.
