DH3751.The coordinates were established by GPS observations
DH3751.and adjusted by the National Geodetic Survey in June 2019.
DH3751
DH3751.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DH3751.been affixed to the stable North American Tectonic Plate.
DH3751
DH3751.The coordinates are valid at the epoch date displayed above
DH3751.which is a decimal equivalence of Year/Month/Day.
DH3751
DH3751.Due to the release of the International GNSS Service (IGS) 2014
DH3751.realization of the International Terrestrial Reference Frame of 2014
DH3751.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DH3751.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DH3751.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DH3751.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DH3751.currently published epoch of 2010.00.
DH3751
DH3751.Additional information on MYCS2 is available at
DH3751.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DH3751.Significant digits in the geoid height do not necessarily reflect accuracy.
DH3751.GEOID18 height accuracy estimate available here.

DH3751.The XYZ, and position/ellipsoidal ht. are equivalent.
DH3751
DH3751.The ellipsoidal height was determined by GPS observations
DH3751.and is referenced to NAD 83.
