Documented History (by the NGS)

01/01/1963 by CGS (MONUMENTED)
DESCRIBED BY COAST AND GEODETIC SURVEY 1963 1.4 MI SW FROM FLORIDA. LOCATED 1.4 MILES SOUTHWEST OF THE FIRE STATION IN FLORIDA. TO REACH FROM THE FIRE STATION IN FLORIDA, DRIVE WEST 0.1 MILE ON U.S. HIGHWAY 24 (HIGH ST.) TO THE FLORIDA BRIDGE ROAD, TURN LEFT AND GO SOUTH ACROSS THE MAUMEE RIVER 0.2 MILE TO COUNTY ROAD Z, TURN RIGHT AND GO 0.7 MILE WEST ON COUNTY ROAD Z TO COUNTY ROAD 18, AND THEN CONTINUE SOUTH ON COUNTY ROAD 18 0.6 MILE TO MARK ON THE FILLING LAND. IT IS 96.2 FEET NORTH OF THE CENTER OF CAMERA TARGET FILLING, 35.0 FEET WEST OF THE CENTERLINE OF COUNTY ROAD 18, 3.0 FEET NORTH OF A TELEPHONE POLE AND 1.0 FOOT WEST OF A WIRE FENCE. A STANDARD REFERENCE MARK DISK STAMPED FILLING NO 2 1963, SET IN A 12 INCH ROUND CONCRETE MONUMENT THAT PROJECTS 2 INCHES.

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. No vertical observational check was made to the station. * This is a POSTED BENCH MARK height. Code NC indicates the bench mark was located on a no-check spur therefore a value was not computed.
  • 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.
