 DC1955.The horizontal coordinates were established by classical geodetic methods
 DC1955.and adjusted by the National Geodetic Survey in June 1996.
 DC1955.The horizontal coordinates are valid at the epoch date displayed above.
 DC1955.The epoch date for horizontal control is a decimal equivalence
 DC1955.of Year/Month/Day.
 DC1955
 DC1955.The NAVD 88 height was computed by applying the VERTCON shift value to
 DC1955.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
 DC1955
 DC1955.The Laplace correction was computed from DEFLEC99 derived deflections.
 DC1955
 DC1955.The geoid height was determined by GEOID99.
