HS3503.The horizontal coordinates were scaled from a topographic map and have
HS3503.an estimated accuracy of +/- 6 seconds.

HS3503.The NAVD 88 height was computed by applying the VERTCON shift value to
HS3503.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
HS3503.The vertical order pertains to the superseded datum.
