DH3759.The coordinates were established by GPS observations
DH3759.and adjusted by the National Geodetic Survey in June 2019.
DH3759
DH3759.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DH3759.been affixed to the stable North American Tectonic Plate.
DH3759
DH3759.The coordinates are valid at the epoch date displayed above
DH3759.which is a decimal equivalence of Year/Month/Day.
DH3759
DH3759.Due to the release of the International GNSS Service (IGS) 2014
DH3759.realization of the International Terrestrial Reference Frame of 2014
DH3759.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DH3759.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DH3759.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DH3759.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DH3759.currently published epoch of 2010.00.
DH3759
DH3759.Additional information on MYCS2 is available at

DH3759.Significant digits in the geoid height do not necessarily reflect accuracy.
DH3759.GEOID18 height accuracy estimate available here.

DH3759.The XYZ, and position/ellipsoidal ht. are equivalent.
DH3759
DH3759.The ellipsoidal height was determined by GPS observations
DH3759.and is referenced to NAD 83.
