DH5827.The coordinates were established by GPS observations
DH5827.and adjusted by the National Geodetic Survey in June 2019.
DH5827
DH5827.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DH5827.been affixed to the stable North American Tectonic Plate.
DH5827
DH5827.The coordinates are valid at the epoch date displayed above
DH5827.which is a decimal equivalence of Year/Month/Day.
DH5827
DH5827.Due to the release of the International GNSS Service (IGS) 2014
DH5827.realization of the International Terrestrial Reference Frame of 2014
DH5827.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DH5827.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DH5827.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DH5827.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DH5827.currently published epoch of 2010.00.
DH5827
DH5827.Additional information on MYCS2 is available at
DH5827.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DH5827.The XYZ, and position/ellipsoidal ht. are equivalent.
DH5827
DH5827.The ellipsoidal height was determined by GPS observations
DH5827.and is referenced to NAD 83.
