DH9024.The coordinates were established by GPS observations
DH9024.and adjusted by the National Geodetic Survey in June 2019.
DH9024
DH9024.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DH9024.been affixed to the stable North American Tectonic Plate.
DH9024
DH9024.The coordinates are valid at the epoch date displayed above
DH9024.which is a decimal equivalence of Year/Month/Day.
DH9024
DH9024.Due to the release of the International GNSS Service (IGS) 2014
DH9024.realization of the International Terrestrial Reference Frame of 2014
DH9024.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DH9024.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DH9024.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DH9024.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DH9024.currently published epoch of 2010.00.
DH9024
DH9024.Additional information on MYCS2 is available at

DH9024.The XYZ, and position/ellipsoidal ht. are equivalent.
DH9024
DH9024.The ellipsoidal height was determined by GPS observations
DH9024.and is referenced to NAD 83.
