DC1958.The horizontal coordinates are valid at the epoch date displayed above. DC1958.The epoch date for horizontal control is a decimal equivalence DC1958.of Year/Month/Day. DC1958 DC1958.The NAVD 88 height was computed by applying the VERTCON shift value to DC1958.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.) DC1958 DC1958.The Laplace correction was computed from DEFLEC99 derived deflections. DC1958 DC1958.The geoid height was determined by GEOID99. DC1958 DC1958; North East Units Scale Converg.
