DG8350.The coordinates were established by GPS observations
DG8350.and adjusted by the National Geodetic Survey in May 2020.
DG8350
DG8350.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DG8350.been affixed to the stable North American Tectonic Plate.
DG8350
DG8350.The coordinates are valid at the epoch date displayed above
DG8350.which is a decimal equivalence of Year/Month/Day.
DG8350
DG8350.Due to the release of the International GNSS Service (IGS) 2014
DG8350.realization of the International Terrestrial Reference Frame of 2014
DG8350.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DG8350.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DG8350.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DG8350.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DG8350.currently published epoch of 2010.00.
DG8350
DG8350.Additional information on MYCS2 is available at

DG8350.Significant digits in the geoid height do not necessarily reflect accuracy.

DG8350.The XYZ, and position/ellipsoidal ht. are equivalent.
DG8350
DG8350.The ellipsoidal height was determined by GPS observations
DG8350.and is referenced to NAD 83.
