First of four BM's found on the Erie Coast Guard property. Had fun looking for these. Managed to get permission to look and even had a nice escort help us out. This was a quick find. Lid was, and still is, slightly open.

Control Text

  • The horizontal coordinates were established by GPS observations and adjusted by the National Geodetic Survey in May 1999.
  • The orthometric height was determined by differential leveling and adjusted by the National Geodetic Survey in June 1991.
  • This Tidal Bench Mark is designated as VM 12811 by the Center for Operational Oceanographic Products and Services.
  • The X, Y, and Z were computed from the position and the ellipsoidal ht.
  • The Laplace correction was computed from DEFLEC99 derived deflections.
  • The ellipsoidal height was determined by GPS observations and is referenced to NAD 83.
  • 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.
