DH5835.The coordinates were established by GPS observations
DH5835.and adjusted by the National Geodetic Survey in May 2021.
DH5835
DH5835.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DH5835.been affixed to the stable North American Tectonic Plate.
DH5835
DH5835.The coordinates are valid at the epoch date displayed above
DH5835.which is a decimal equivalence of Year/Month/Day.
DH5835
DH5835.Due to the release of the International GNSS Service (IGS) 2014
DH5835.realization of the International Terrestrial Reference Frame of 2014
DH5835.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DH5835.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DH5835.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DH5835.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DH5835.currently published epoch of 2010.00.
DH5835
DH5835.Additional information on MYCS2 is available at
DH5835.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DH5835.The XYZ, and position/ellipsoidal ht. are equivalent.
DH5835
DH5835.The ellipsoidal height was determined by GPS observations
DH5835.and is referenced to NAD 83.
