DH5839.The coordinates were established by GPS observations
DH5839.and adjusted by the National Geodetic Survey in June 2019.
DH5839
DH5839.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DH5839.been affixed to the stable North American Tectonic Plate.
DH5839
DH5839.The coordinates are valid at the epoch date displayed above
DH5839.which is a decimal equivalence of Year/Month/Day.
DH5839
DH5839.Due to the release of the International GNSS Service (IGS) 2014
DH5839.realization of the International Terrestrial Reference Frame of 2014
DH5839.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DH5839.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DH5839.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DH5839.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DH5839.currently published epoch of 2010.00.
DH5839
DH5839.Additional information on MYCS2 is available at

DH5839.The XYZ, and position/ellipsoidal ht. are equivalent.
DH5839
DH5839.The ellipsoidal height was determined by GPS observations
DH5839.and is referenced to NAD 83.
