DG9783.The coordinates were established by GPS observations
DG9783.and adjusted by the National Geodetic Survey in June 2019.
DG9783
DG9783.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DG9783.been affixed to the stable North American Tectonic Plate.
DG9783
DG9783.The coordinates are valid at the epoch date displayed above
DG9783.which is a decimal equivalence of Year/Month/Day.
DG9783
DG9783.Due to the release of the International GNSS Service (IGS) 2014
DG9783.realization of the International Terrestrial Reference Frame of 2014
DG9783.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DG9783.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DG9783.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DG9783.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DG9783.currently published epoch of 2010.00.
DG9783
DG9783.Additional information on MYCS2 is available at
DG9783.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DG9783.Significant digits in the geoid height do not necessarily reflect accuracy.
DG9783.GEOID18 height accuracy estimate available here.

DG9783.The XYZ, and position/ellipsoidal ht. are equivalent.
DG9783
DG9783.The ellipsoidal height was determined by GPS observations
DG9783.and is referenced to NAD 83.
