GR1805.The horizontal coordinates were established by classical geodetic methods
GR1805.and adjusted by the National Geodetic Survey in June 1998.
GR1805.
GR1805.The NAVD 88 height was computed by applying the VERTCON shift value to
GR1805.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
GR1805
GR1805.The Laplace correction was computed from DEFLEC12A derived deflections.
