DESCRIBED BY NATIONAL GEODETIC SURVEY 1991 IN ALBUQUERQUE, AT THE INTERSECTION OF GIBSON BOULEVARD AND BUENA VISTA STREET, IN A CONCRETE RAIN GUTTER AT THE WEST END OF A MEDIAN, 280.4 M (919.9 FT) WEST OF THE CENTER OF THE STREET, 7.9 M (25.9 FT) SOUTH OF THE CENTER OF THE WESTBOUND LANES OF THE BOULEVARD, 7.6 M (24.9 FT) NORTH OF AND LEVEL WITH THE CENTER OF THE EASTBOUND LANES OF THE BOULEVARD, AND 0.2 M (0.7 FT) WEST OF THE WEST END OF THE MEDIAN.

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 1995.
  • 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.
