DG9771.The coordinates were established by GPS observations
DG9771.and adjusted by the National Geodetic Survey in April 2022.
DG9771
DG9771.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DG9771.been affixed to the stable North American Tectonic Plate.
DG9771
DG9771.The coordinates are valid at the epoch date displayed above
DG9771.which is a decimal equivalence of Year/Month/Day.
DG9771
DG9771.Due to the release of the International GNSS Service (IGS) 2014
DG9771.realization of the International Terrestrial Reference Frame of 2014
DG9771.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DG9771.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DG9771.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DG9771.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DG9771.currently published epoch of 2010.00.
DG9771
DG9771.Additional information on MYCS2 is available at

DG9771.Significant digits in the geoid height do not necessarily reflect accuracy.
DG9771.GEOID18 height accuracy estimate available here.

DG9771.The XYZ, and position/ellipsoidal ht. are equivalent.
DG9771
DG9771.The ellipsoidal height was determined by GPS observations
DG9771.and is referenced to NAD 83.
