The horizontal coordinates were established by GPS observations and adjusted by the SOUTH CAROLINA GEODETIC SURVEY in September 2010.
The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007). See National Readjustment for more information.
The horizontal coordinates are valid at the epoch date displayed above which is a decimal equivalence of Year/Month/Day.
The orthometric height was determined by GPS observations and a high-resolution geoid model using precise GPS observation and processing techniques.
The X, Y, and Z were computed from the position and the ellipsoidal ht.
The Laplace correction was computed from DEFLEC09 derived deflections.
The ellipsoidal height was determined by GPS observations and is referenced to NAD 83.
The geoid height was determined by GEOID09.
