Documented History (by the NGS)
|1/1/1967 by CGS (MONUMENTED)
|DESCRIBED BY COAST AND GEODETIC SURVEY 1967
IN TRENTON. AT TRENTON, AT THE CROSSING OF STATE HIGHWAY 170 OVER THE UNION PACIFIC RAILROAD, ABOUT 300 FEET WEST OF THE MAIN TRACK, 118 1/2 FEET NORTH OF THE CENTER LINE OF THE HIGHWAY, SET VERTICALLY IN THE SOUTH FACE OF TRENTON FEED CO-OP BUILDING, 17 1/2 FEET EAST OF THE CENTER OF THE DOOR OF THE OFFICE BUILDING, 0.8 FOOT WEST OF THE SOUTHEAST CORNER OF THE BUILDING, AND ABOUT 0.6 FOOT ABOVE THE GROUND.
- 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.
