DH3772.The coordinates were established by GPS observations
DH3772.and adjusted by the National Geodetic Survey in June 2019.
DH3772
DH3772.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DH3772.been affixed to the stable North American Tectonic Plate.
DH3772
DH3772.The coordinates are valid at the epoch date displayed above
DH3772.which is a decimal equivalence of Year/Month/Day.
DH3772
DH3772.Due to the release of the International GNSS Service (IGS) 2014
DH3772.realization of the International Terrestrial Reference Frame of 2014
DH3772.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DH3772.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DH3772.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DH3772.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DH3772.currently published epoch of 2010.00.
DH3772
DH3772.Additional information on MYCS2 is available at

DH3772.Significant digits in the geoid height do not necessarily reflect accuracy.
DH3772.GEOID18 height accuracy estimate available here.

DH3772.The XYZ, and position/ellipsoidal ht. are equivalent.
DH3772
DH3772.The ellipsoidal height was determined by GPS observations
DH3772.and is referenced to NAD 83.
