RECOVERY NOTE BY NATIONAL GEODETIC SURVEY 1982 23.6 KM (14.7 MI) EAST ALONG US HIGHWAY 66 FROM THE ATCHISON, TOPEKA AND SANTA FE RAILROAD STATION IN SELIGMAN, ABOUT 0.35 MILE NORTHWEST OF SOME PIPELINE RISERS, NEAR THE HIGHEST POINT IN THE HIGHWAY, 29.2 METERS (96 FT) SOUTH OF THE CENTERLINE OF THE HIGHWAY, 10.3 METERS (34.7 FT) WEST OF STATION PENE, 1.2 METERS (4 FT) NORTH OF A FENCE.

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.
