DC1957.The horizontal coordinates are valid at the epoch date displayed above. DC1957.The epoch date for horizontal control is a decimal equivalence DC1957.of Year/Month/Day. DC1957 DC1957.The NAVD 88 height was computed by applying the VERTCON shift value to DC1957.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.) DC1957 DC1957.The Laplace correction was computed from DEFLEC99 derived deflections. DC1957 DC1957.The geoid height was determined by GEOID99. DC1957 DC1957; North East Units Scale Converg.
