Documented History (by the NGS)

01/01/1985 by SLCPS (MONUMENTED)
09/16/1997 by NGS (GOOD)
DESCRIBED BY NATIONAL GEODETIC SURVEY 1997 (GAS) IN SALT LAKE CITY, AT THE INTERSECTION OF SOUTH TEMPLE AND 300 EAST STREETS, NEAR THE NORTHWEST CORNER OF A CONCRETE CLEAN OUT BOX, 13.1 M (43.0 FT) SOUTH OF THE CENTER OF THE EASTBOUND LANES OF TEMPLE STREET, 10.8 M (35.4 FT) EAST OF THE CENTER OF EAST STREET, 3.4 M (11.2 FT) SOUTH OF UTILITY LIGHT POLE NUMBER 35 WITH A GUY CABLE, 0.2 M (0.7 FT) ABOVE THE LEVEL OF EAST STREET, AND FLUSH WITH THE GROUND SURFACE.

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 April 2000.
  • 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.
