DX4927.The horizontal coordinates are valid at the epoch date displayed above. DX4927.The epoch date for horizontal control is a decimal equivalence DX4927.of Year/Month/Day. DX4927 DX4927.The NAVD 88 height was computed by applying the VERTCON shift value to DX4927.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.) DX4927 DX4927.The Laplace correction was computed from DEFLEC99 derived deflections. DX4927 DX4927.The geoid height was determined by GEOID99. DX4927 DX4927; North East Units Scale Converg.
