DG9751.The coordinates were established by GPS observations
DG9751.and adjusted by the National Geodetic Survey in June 2019.
DG9751
DG9751.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DG9751.been affixed to the stable North American Tectonic Plate.
DG9751
DG9751.The coordinates are valid at the epoch date displayed above
DG9751.which is a decimal equivalence of Year/Month/Day.
DG9751
DG9751.Due to the release of the International GNSS Service (IGS) 2014
DG9751.realization of the International Terrestrial Reference Frame of 2014
DG9751.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DG9751.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DG9751.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DG9751.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DG9751.currently published epoch of 2010.00.
DG9751
DG9751.Additional information on MYCS2 is available at
DG9751.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DG9751.The orthometric height was determined by differential leveling and
DG9751.adjusted by the NATIONAL GEODETIC SURVEY
DG9751.in September 2022.
DG9751
DG9751.Significant digits in the geoid height do not necessarily reflect accuracy.
DG9751.GEOID18 height accuracy estimate available here.

DG9751.The XYZ, and position/ellipsoidal ht. are equivalent.
DG9751
DG9751.The ellipsoidal height was determined by GPS observations
DG9751.and is referenced to NAD 83.
