SB0974.The horizontal coordinates were established by classical geodetic methods
SB0974.and adjusted by the National Geodetic Survey in December 1991.
SB0974
SB0974.The NAVD 88 height was computed by applying the VERTCON shift value to
SB0974.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
SB0974
SB0974.The Laplace correction was computed from DEFLEC99 derived deflections.
SB0974
SB0974.The geoid height was determined by GEOID99.
