Documented History (by the NGS)

01/01/1935 by CGS (MONUMENTED)
DESCRIBED BY COAST AND GEODETIC SURVEY 1935 2.1 MI W FROM PERRY. 2.1 MILES WEST ALONG STATE HIGHWAY 26 FROM A SCHOOL AT PERRY, RALLS COUNTY, OPPOSITE A TWO-STORY WHITE FARMHOUSE, 65 FEET WEST OF A SMALL CONCRETE CULVERT, 50 FEET SOUTH OF THE CENTERLINE OF THE HIGHWAY, AND 1 1/2 FEET NORTH OF A FENCE. A STANDARD DISK, STAMPED Z 132 1935 AND SET IN THE TOP OF A CONCRETE POST.

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.
