JS4673.The horizontal coordinates were established by GPS observations JS4673.and adjusted by the National Geodetic Survey in February 2007. JS4673 JS4673.The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007). JS4673.See National Readjustment for more information. JS4673.The horizontal coordinates are valid at the epoch date displayed above. JS4673.The epoch date for horizontal control is a decimal equivalence JS4673.of Year/Month/Day. JS4673 JS4673.The orthometric height was determined by GPS observations and a JS4673.high-resolution geoid model. JS4673 JS4673.Photographs are available for this station. JS4673 JS4673.The X, Y, and Z were computed from the position and the ellipsoidal ht. JS4673 JS4673.The Laplace correction was computed from DEFLEC09 derived deflections. JS4673 JS4673.The ellipsoidal height was determined by GPS observations JS4673.and is referenced to NAD 83. JS4673 JS4673.The geoid height was determined by GEOID09.
