DL7638.The coordinates were established by GPS observations
DL7638.and adjusted by the National Geodetic Survey in June 2019.
DL7638
DL7638.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL7638.been affixed to the stable North American Tectonic Plate.
DL7638
DL7638.The coordinates are valid at the epoch date displayed above
DL7638.which is a decimal equivalence of Year/Month/Day.
DL7638
DL7638.Due to the release of the International GNSS Service (IGS) 2014
DL7638.realization of the International Terrestrial Reference Frame of 2014
DL7638.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL7638.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL7638.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL7638.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL7638.currently published epoch of 2010.00.
DL7638
DL7638.Additional information on MYCS2 is available at
DL7638.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DL7638.The XYZ, and position/ellipsoidal ht. are equivalent.
DL7638
DL7638.The ellipsoidal height was determined by GPS observations
DL7638.and is referenced to NAD 83.
