DL6429.The coordinates were established by GPS observations
DL6429.and adjusted by the National Geodetic Survey in June 2021.
DL6429
DL6429.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL6429.been affixed to the stable North American Tectonic Plate.
DL6429
DL6429.The coordinates are valid at the epoch date displayed above
DL6429.which is a decimal equivalence of Year/Month/Day.
DL6429
DL6429.Due to the release of the International GNSS Service (IGS) 2014
DL6429.realization of the International Terrestrial Reference Frame of 2014
DL6429.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL6429.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL6429.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL6429.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL6429.currently published epoch of 2010.00.
DL6429
DL6429.Additional information on MYCS2 is available at
DL6429.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DL6429.The XYZ, and position/ellipsoidal ht. are equivalent.
DL6429
DL6429.The ellipsoidal height was determined by GPS observations
DL6429.and is referenced to NAD 83.
