DH5833.The coordinates were established by GPS observations
DH5833.and adjusted by the National Geodetic Survey in June 2019.
DH5833
DH5833.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DH5833.been affixed to the stable North American Tectonic Plate.
DH5833
DH5833.The coordinates are valid at the epoch date displayed above
DH5833.which is a decimal equivalence of Year/Month/Day.
DH5833
DH5833.Due to the release of the International GNSS Service (IGS) 2014
DH5833.realization of the International Terrestrial Reference Frame of 2014
DH5833.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DH5833.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DH5833.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DH5833.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DH5833.currently published epoch of 2010.00.
DH5833
DH5833.Additional information on MYCS2 is available at
DH5833.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DH5833.The XYZ, and position/ellipsoidal ht. are equivalent.
DH5833
DH5833.The ellipsoidal height was determined by GPS observations
DH5833.and is referenced to NAD 83.
