DH5825.The coordinates were established by GPS observations
DH5825.and adjusted by the National Geodetic Survey in June 2019.
DH5825
DH5825.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DH5825.been affixed to the stable North American Tectonic Plate.
DH5825
DH5825.The coordinates are valid at the epoch date displayed above
DH5825.which is a decimal equivalence of Year/Month/Day.
DH5825
DH5825.Due to the release of the International GNSS Service (IGS) 2014
DH5825.realization of the International Terrestrial Reference Frame of 2014
DH5825.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DH5825.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DH5825.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DH5825.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DH5825.currently published epoch of 2010.00.
DH5825
DH5825.Additional information on MYCS2 is available at
DH5825.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DH5825.The XYZ, and position/ellipsoidal ht. are equivalent.
DH5825
DH5825.The ellipsoidal height was determined by GPS observations
DH5825.and is referenced to NAD 83.
