DG8221.The coordinates were established by GPS observations
DG8221.and adjusted by the National Geodetic Survey in June 2019.
DG8221
DG8221.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DG8221.been affixed to the stable North American Tectonic Plate.
DG8221
DG8221.The coordinates are valid at the epoch date displayed above
DG8221.which is a decimal equivalence of Year/Month/Day.
DG8221
DG8221.Due to the release of the International GNSS Service (IGS) 2014
DG8221.realization of the International Terrestrial Reference Frame of 2014
DG8221.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DG8221.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DG8221.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DG8221.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DG8221.currently published epoch of 2010.00.
DG8221
DG8221.Additional information on MYCS2 is available at
DG8221.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DG8221.Significant digits in the geoid height do not necessarily reflect accuracy.
DG8221.GEOID18 height accuracy estimate available here.

DG8221.The XYZ, and position/ellipsoidal ht. are equivalent.
DG8221
DG8221.The ellipsoidal height was determined by GPS observations
DG8221.and is referenced to NAD 83.
