DH4516.The coordinates were established by GPS observations
DH4516.and adjusted by the National Geodetic Survey in March 2023.
DH4516
DH4516.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DH4516.been affixed to the stable North American Tectonic Plate.
DH4516
DH4516.The coordinates are valid at the epoch date displayed above
DH4516.which is a decimal equivalence of Year/Month/Day.
DH4516
DH4516.Due to the release of the International GNSS Service (IGS) 2014
DH4516.realization of the International Terrestrial Reference Frame of 2014
DH4516.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DH4516.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DH4516.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DH4516.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DH4516.currently published epoch of 2010.00.
DH4516
DH4516.Additional information on MYCS2 is available at

DH4516.The XYZ, and position/ellipsoidal ht. are equivalent.
DH4516
DH4516.The ellipsoidal height was determined by GPS observations
DH4516.and is referenced to NAD 83.
