TV1513.The horizontal coordinates were established by GPS observations
TV1513.and adjusted by the National Geodetic Survey in June 2012.
TV1513
TV1513.NAD 83(2011) refers to NAD 83 coordinates where the reference
TV1513.frame has been affixed to the stable North American tectonic plate. See
TV1513.NA2011 for more information. for more information.
TV1513
TV1513.The horizontal coordinates are valid at the epoch date displayed above
TV1513.which is a decimal equivalence of Year/Month/Day.
TV1513
TV1513.The orthometric height was determined by differential leveling and
TV1513.adjusted by the CEN OPER OCEANOG PROD+SVCS
TV1513.in November 2002.
TV1513
TV1513.This bench mark was chosen by the National Geodetic Survey
TV1513.(NGS) to serve as the datum origin point for the Puerto Rico Vertical
TV1513.Datum of 2002 (PRVD02). The PRVD02 height for this point was adopted by
TV1513.NGS to be exactly 1.334 meters which is identical to the LMSL height of
TV1513.this bench mark for National Tidal Datum 1960-1978 as determined by
TV1513.Center for Operational Oceanographics Products and Services (CO-OPS) in
TV1513.November 2002.
TV1513
TV1513.Information on the Tidal Bench Mark designated as VM 1386 and its datum origin
TV1513.point is located at CENTER FOR OPERATIONAL OCEANOGRAPHIC PRODUCTS AND SERVICES
TV1513
TV1513.Photographs are available for this station.
TV1513
TV1513.The X, Y, and Z were computed from the position and the ellipsoidal ht.
TV1513
TV1513.The Laplace correction was computed from DEFLEC12A derived deflections.
TV1513
TV1513.The ellipsoidal height was determined by GPS observations
TV1513.and is referenced to NAD 83.
TV1513
TV1513.The dynamic height is computed by dividing the NAVD 88
TV1513.geopotential number by the normal gravity value computed on the
TV1513.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
TV1513.degrees latitude (g = 980.6199 gals.).
TV1513
TV1513.The modeled gravity was interpolated from observed gravity values.
TV1513
TV1513. The following values were computed from the NAD 83(2011) position.
