DH8821.The coordinates were established by GPS observations
DH8821.and adjusted by the National Geodetic Survey in June 2019.
DH8821
DH8821.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DH8821.been affixed to the stable North American Tectonic Plate.
DH8821
DH8821.The coordinates are valid at the epoch date displayed above
DH8821.which is a decimal equivalence of Year/Month/Day.
DH8821
DH8821.Due to the release of the International GNSS Service (IGS) 2014
DH8821.realization of the International Terrestrial Reference Frame of 2014
DH8821.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DH8821.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DH8821.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DH8821.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DH8821.currently published epoch of 2010.00.
DH8821
DH8821.Additional information on MYCS2 is available at
DH8821.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DH8821.Significant digits in the geoid height do not necessarily reflect accuracy.
DH8821.GEOID18 height accuracy estimate available here.

DH8821.The XYZ, and position/ellipsoidal ht. are equivalent.
DH8821
DH8821.The ellipsoidal height was determined by GPS observations
DH8821.and is referenced to NAD 83.
