EW1930.The horizontal coordinates were scaled from a topographic map and have
EW1930.an estimated accuracy of +/- 6 seconds.

EW1930.The NAVD 88 height was computed by applying the VERTCON shift value to
EW1930.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
EW1930.The vertical order pertains to the superseded datum.
