FORT SUMTER BATTERY REF 2 - PID CJ0866 - U.S. Benchmarks on Waymarking.com

This benchmark is covered over with roofing material. The roof started leaking a few years ago and had to be tarred over. All that is viewable now is the impression of its location. The actual BM is still in place.

CJ0866.The horizontal coordinates were established by GPS observations
CJ0866.and adjusted by the National Geodetic Survey in February 2007.
CJ0866
CJ0866.The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007).
CJ0866.See National Readjustment for more information.
CJ0866.The horizontal coordinates are valid at the epoch date displayed above.
CJ0866.The epoch date for horizontal control is a decimal equivalence
CJ0866.of Year/Month/Day.
CJ0866
CJ0866.The orthometric height was determined by GPS observations and a
CJ0866.high-resolution geoid model using precise GPS observation and
CJ0866.processing techniques.
CJ0866
CJ0866.The X, Y, and Z were computed from the position and the ellipsoidal ht.
CJ0866
CJ0866.The Laplace correction was computed from DEFLEC99 derived deflections.
CJ0866
CJ0866.The ellipsoidal height was determined by GPS observations
CJ0866.and is referenced to NAD 83.
CJ0866
CJ0866.The geoid height was determined by GEOID03.
