DG9791.The coordinates were established by GPS observations
DG9791.and adjusted by the National Geodetic Survey in June 2019.
DG9791
DG9791.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DG9791.been affixed to the stable North American Tectonic Plate.
DG9791
DG9791.The coordinates are valid at the epoch date displayed above
DG9791.which is a decimal equivalence of Year/Month/Day.
DG9791
DG9791.Due to the release of the International GNSS Service (IGS) 2014
DG9791.realization of the International Terrestrial Reference Frame of 2014
DG9791.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DG9791.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DG9791.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DG9791.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DG9791.currently published epoch of 2010.00.
DG9791
DG9791.Additional information on MYCS2 is available at
DG9791.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DG9791.Significant digits in the geoid height do not necessarily reflect accuracy.
DG9791.GEOID18 height accuracy estimate available here.

DG9791.The XYZ, and position/ellipsoidal ht. are equivalent.
DG9791
DG9791.The ellipsoidal height was determined by GPS observations
DG9791.and is referenced to NAD 83.
