JT9134  VERT ORDER  -  SECOND    CLASS II (See Below)
JT9134
JT9134.The horizontal coordinates were scaled from a topographic map and have
JT9134.an estimated accuracy of +/- 6 seconds.
JT9134
JT9134.The NAVD 88 height was computed by applying the VERTCON shift value to
JT9134.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
JT9134.The vertical order pertains to the superseded datum.
JT9134
JT9134.The geoid height was determined by GEOID99.
