 ES1140.The horizontal coordinates were established by classical geodetic methods
 ES1140.and adjusted by the National Geodetic Survey in August 1993.
 ES1140.
 ES1140.The NAVD 88 height was computed by applying the VERTCON shift value to
 ES1140.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)

 ES1140.Significant digits in the geoid height do not necessarily reflect accuracy.
 ES1140.GEOID18 height accuracy estimate available here.
