 AA4484
 AA4484.The horizontal coordinates were scaled from a topographic map and have
 AA4484.an estimated accuracy of +/- 6 seconds.
 AA4484
 AA4484.The NAVD 88 height was computed by applying the VERTCON shift value to
 AA4484.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
 AA4484.The vertical order pertains to the superseded datum.
 AA4484
 AA4484.The geoid height was determined by GEOID99.
