 QA0689.The horizontal coordinates were established by classical geodetic methods
 QA0689.and adjusted by the National Geodetic Survey in July 1992.
 QA0689.
 QA0689.The NAVD 88 height was computed by applying the VERTCON shift value to
 QA0689.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
 QA0689
 QA0689.Significant digits in the geoid height do not necessarily reflect accuracy.
 QA0689.GEOID18 height accuracy estimate available here.
