DG9774.The coordinates were established by GPS observations
DG9774.and adjusted by the National Geodetic Survey in December 2022.
DG9774
DG9774.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DG9774.been affixed to the stable North American Tectonic Plate.
DG9774
DG9774.The coordinates are valid at the epoch date displayed above
DG9774.which is a decimal equivalence of Year/Month/Day.
DG9774
DG9774.Due to the release of the International GNSS Service (IGS) 2014
DG9774.realization of the International Terrestrial Reference Frame of 2014
DG9774.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DG9774.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DG9774.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DG9774.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DG9774.currently published epoch of 2010.00.
DG9774
DG9774.Additional information on MYCS2 is available at
DG9774.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DG9774.Significant digits in the geoid height do not necessarily reflect accuracy.
DG9774.GEOID18 height accuracy estimate available here.

DG9774.The XYZ, and position/ellipsoidal ht. are equivalent.
DG9774
DG9774.The ellipsoidal height was determined by GPS observations
DG9774.and is referenced to NAD 83.
