I drive this road all the time when I go down to San Diego... Ive only recently started hunting benchmarks but I'm surprised Ive never seen this from the road and wondered what it was.

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 1992. * This is a POSTED BENCH MARK height. Code B indicates a distribution rate of 1.1 thru 2.0 mm/km.
  • 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.
