 DL3908.The horizontal coordinates were established by autonomous hand held GPS
 DL3908.observations and have an estimated accuracy of +/- 10 meters.

 DL3908.The orthometric height was determined by differential leveling and
 DL3908.adjusted by the NATIONAL GEODETIC SURVEY
 DL3908.in April 2012.

 DL3908.This bench mark was chosen by the National Geodetic Survey 
 DL3908.(NGS) to serve as the datum origin point for the Virgin Island Vertical 
 DL3908.Datum of 2009 (VIVD09) as realized on the island of St. Thomas. The 
 DL3908.VIVD09 height for this point was adopted by NGS to be exactly 1.552 
 DL3908.meters which is identical to the LMSL height of this bench mark for 
 DL3908.National Tidal Datum 1983-2001 as determined by Center for Operational 
 DL3908.Oceanographics Products and Services (CO-OPS) in April 2003.
