Documented History (by the NGS)

01/01/1935 by CGS (MONUMENTED)
DESCRIBED BY COAST AND GEODETIC SURVEY 1935 (BHR) THIS INTERSECTION STATION IS LOCATED 18.65 FEET TO THE NE OF THE EDGE OF CONCRETE ROAD LEADING FROM SOMERS POINT TO OCEAN CITY, N.J. AND 0.85 MILE FROM THE SOMERS POINT END OF WORLD WAR MEMORIAL BRIDGE OVER SHIP CHANNEL. IT IS 16.60 FEET FROM THE CENTER OF THE SW RAIL OF THE SHORE FAST LINE TRACKS. IT IS ALSO 210.1 FEET FROM SE END JUNCTION OF INNER RAILS OF MAIN LINE AND SIDE TRACK. SURFACE, UNDERGROUND AND REFERENCE MARKS ARE STANDARD BRONZE DISKS SET IN CONCRETE AS DESCRIBED IN NOTES 1A AND 11A. REFERENCE MARKS ARE IN LINE WITH STATION, REFERENCE MARK NO. 1 TO SE AND REFERENCE MARK NO. 2 TO NW. REFERENCE MARK NO.1 IS 18.50 FEET FROM CENTER OF ACE SYSTEM POWER POLE NO. 8173. REFERENCE MARK NO. 2 IS 26.25 FEET FROM POWER POLE NO. 8174. ALL DISKS STAMPED LINE 1935. REFERENCE MARKS STAMPED 1 AND 2 RESPECTIVELY. HEIGHT OF SIGNAL ABOVE STATION MARK - 5 METERS
01/01/1950 by CGS (GOOD)
RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1950 (HFG) STATION AND REFERENCE MARKS WERE RECOVERED IN GOOD CONDITION. THE DISTANCES TO THE REFERENCE MARKS WERE MEASURED WITH A STEEL TAPE AND FOUND TO BE CORRECT. THE PUBLISHED DESCRIPTION IS ADEQUATE AND CORRECT WITH THE FOLLOWING EXCEPTIONS-- THE SHORE FAST LINE TRACKS NO LONGER EXIST. STATION MARK IS 115.7 FEET SE OF A.C.E. POLE NO. 8174, 88.5 FEET NW OF A.C.E. POLE 8173, 37.6 FEET E OF THE NW CORNER OF HIGHWAY SLAB NO. 28, AND 23.2 FEET N OF THE SE CORNER OF CONCRETE HIGHWAY SLAB NO. 28. REFERENCE MARK 1 IS 18.5 FEET N OF A.C.E. POLE NO. 8173 AND 20.5 FEET NE OF THE NE EDGE OF THE CONCRETE HIGHWAY. REFERENCE MARK 2 IS 26.2 FEET E OF A.C.E. POLE NO. 8174 AND 19.6 FEET NE OF THE NE EDGE OF THE CONCRETE HIGHWAY.
01/01/1964 by CGS (GOOD)
RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1964 (RG) THE STATION, RM 1 AND RM 2 WERE RECOVERED IN GOOD CONDITION AS DESCRIBED. THE EAST CORNER OF THE POST FOR LINE RM 1 HAS BEEN CHIPPED OFF, HOWEVER THE POST IS STILL SOLID AND IN GOOD CONDITION. THE NORTH CORNER OF LINE RM 2 HAS BEEN CHIPPED OFF, HOWEVER THE POST IS STILL SOLID AND IN GOOD CONDITION.
01/01/1964 by CGS (GOOD)
RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1964 1.4 MI NW FROM OCEAN CITY. 1.45 MILES NORTHWEST ALONG STATE HIGHWAY 52 (9TH STREET IN OCEAN CITY) FROM THE CITY HALL IN OCEAN CITY, 0.55 MILE SOUTHEAST OF THE SOUTHEAST END OF BRIDGE OVER SHIP CHANNEL, 0.2 MILE NORTHWEST OF THE NORTHWEST END OF BRIDGE OVER RAINBOW CHANNEL, 39 FEET NORTHEAST OF THE CENTER LINE OF THE HIGHWAY, 88 1/2 FEET NORTHWEST OF POWER POLE NO. 8173, 91.5 FEET SOUTHEAST OF LINE RM 2 DESCRIBED, 73.8 FEET NORTHWEST OF LINE RM 1 DESCRIBED, ABOUT LEVEL WITH THE HIGHWAY AND SET IN THE TOP OF A CONCRETE POST THAT IS FLUSH WITH THE GROUND.

RECOVERY NOTE BY NATIONAL GEODETIC SURVEY 1979 RECOVERED IN GOOD CONDITION.

Control Text

  • The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in September 1999.
  • The orthometric height was determined by differential leveling and adjusted by the National Geodetic Survey in June 1991.
  • The Laplace correction was computed from DEFLEC99 derived deflections.
  • 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.
