DH3842.The coordinates were established by GPS observations
DH3842.and adjusted by the National Geodetic Survey in June 2022.
DH3842
DH3842.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DH3842.been affixed to the stable North American Tectonic Plate.
DH3842
DH3842.The coordinates are valid at the epoch date displayed above
DH3842.which is a decimal equivalence of Year/Month/Day.
DH3842
DH3842.Due to the release of the International GNSS Service (IGS) 2014
DH3842.realization of the International Terrestrial Reference Frame of 2014
DH3842.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DH3842.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DH3842.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DH3842.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DH3842.currently published epoch of 2010.00.
DH3842
DH3842.Additional information on MYCS2 is available at
DH3842.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DH3842.Significant digits in the geoid height do not necessarily reflect accuracy.
DH3842.GEOID18 height accuracy estimate available here.

DH3842
DH3842.The XYZ, and position/ellipsoidal ht. are equivalent.
DH3842
DH3842.The ellipsoidal height was determined by GPS observations
DH3842.and is referenced to NAD 83.
