IN SALT LAKE CITY, AT THE INTERSECTION OF 400 WEST AND 300 NORTH STREETS, SET VERTICALLY IN THE WEST FACE OF THE HEATING PLANT FOR WEST HIGH SCHOOL, 19.9 M (65.3 FT) EAST OF THE CENTERLINE OF THE NORTHBOUND LANES OF WEST STREET, 10.9 M (35.8 FT) SOUTH OF THE CENTERLINE OF NORTH STREET, 7.0 M (23.0 FT) EAST OF A SIGNAL LIGHT POLE, 3.1 M (10.2 FT) SOUTH OF A UTILITY POLE WITH 5 GUY CABLES, 0.5 M (1.6 FT) ABOVE THE LEVEL OF WEST STREET, AND 0.2 M (0.7 FT) SOUTH OF THE NORTHWEST CORNER OF THE BUILDING.
- 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 September 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.
