DG5315.The coordinates were established by GPS observations
DG5315.and adjusted by the National Geodetic Survey in June 2019.
DG5315
DG5315.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DG5315.been affixed to the stable North American Tectonic Plate.
DG5315
DG5315.The coordinates are valid at the epoch date displayed above
DG5315.which is a decimal equivalence of Year/Month/Day.
DG5315
DG5315.Due to the release of the International GNSS Service (IGS) 2014
DG5315.realization of the International Terrestrial Reference Frame of 2014
DG5315.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DG5315.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DG5315.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DG5315.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DG5315.currently published epoch of 2010.00.
DG5315
DG5315.Additional information on MYCS2 is available at

DG5315.** This station is in an area of known vertical motion. If an
DG5315.** orthometric height was ever established but is not available
DG5315.** in the current survey control section, the orthometric height
DG5315.** is considered suspect. Suspect heights are available in the
DG5315.** superseded section only if requested.
DG5315
DG5315.Significant digits in the geoid height do not necessarily reflect accuracy.

DG5315.The PID for the CORS L1 Phase Center is DR3565.

DG5315.The XYZ, and position/ellipsoidal ht. are equivalent.
DG5315
DG5315.The ellipsoidal height was determined by GPS observations
DG5315.and is referenced to NAD 83.
