Documented History (by the NGS)

01/01/1984 by NGS (MONUMENTED)
DESCRIBED BY NATIONAL GEODETIC SURVEY 1984 21.2 KM (13.15 MI) SOUT FROM MANILA. 21.2 KM (13.15 MI) SOUTHERLY ALONG STATE HIGHWAY 44 FROM ITS JUNCTION WITH STATE HIGHWAY 43 IN MANILA, 0.5 KM (0.3 MI) SOUTHEAST OF MILEPOST 15, 22.3 M (73.2 FT) SOUTHWEST OF THE CENTERLINE OF THE HIGHWAY, AND 8.9 M (29.2 FT) NORTHWEST OF THE CENTERLINE OF THE PAVED ROAD. NOTE=REFUSAL WAS REACHED AT 4.0 FT. ACCESS TO THE DATUM POINT IS THROUGH A 5-INCH LOGO CAP. THE MARK IS 0.3 METERS SE FROM A WITNESS POST THE MARK IS 0.3 M BELOW THE HIGHWAY.

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.
