JT0132.The horizontal coordinates were scaled from a topographic map and have
JT0132.an estimated accuracy of +/- 6 seconds.
JT0132
JT0132.The NAVD 88 height was computed by applying the VERTCON shift value to
JT0132.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
JT0132.The vertical order pertains to the superseded datum.
