DG5936.The coordinates were established by GPS observations
DG5936.and adjusted by the National Geodetic Survey in May 2021.
DG5936
DG5936.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DG5936.been affixed to the stable North American Tectonic Plate.
DG5936
DG5936.The coordinates are valid at the epoch date displayed above
DG5936.which is a decimal equivalence of Year/Month/Day.
DG5936
DG5936.Due to the release of the International GNSS Service (IGS) 2014
DG5936.realization of the International Terrestrial Reference Frame of 2014
DG5936.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DG5936.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DG5936.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DG5936.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DG5936.currently published epoch of 2010.00.
DG5936
DG5936.Additional information on MYCS2 is available at
DG5936.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DG5936.Significant digits in the geoid height do not necessarily reflect accuracy.
DG5936.GEOID18 height accuracy estimate available here.

DG5936.The XYZ, and position/ellipsoidal ht. are equivalent.
DG5936
DG5936.The ellipsoidal height was determined by GPS observations
DG5936.and is referenced to NAD 83.
