DH4108.The coordinates were established by GPS observations
DH4108.and adjusted by the National Geodetic Survey in June 2019.
DH4108
DH4108.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DH4108.been affixed to the stable North American Tectonic Plate.
DH4108
DH4108.The coordinates are valid at the epoch date displayed above
DH4108.which is a decimal equivalence of Year/Month/Day.
DH4108
DH4108.Due to the release of the International GNSS Service (IGS) 2014
DH4108.realization of the International Terrestrial Reference Frame of 2014
DH4108.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DH4108.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DH4108.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DH4108.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DH4108.currently published epoch of 2010.00.
DH4108
DH4108.Additional information on MYCS2 is available at

DH4108.The XYZ, and position/ellipsoidal ht. are equivalent.
DH4108
DH4108.The ellipsoidal height was determined by GPS observations
DH4108.and is referenced to NAD 83.
