DL3174.The coordinates were established by GPS observations
DL3174.and adjusted by the National Geodetic Survey in March 2022.
DL3174
DL3174.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL3174.been affixed to the stable North American Tectonic Plate.
DL3174
DL3174.The coordinates are valid at the epoch date displayed above
DL3174.which is a decimal equivalence of Year/Month/Day.
DL3174
DL3174.Due to the release of the International GNSS Service (IGS) 2014
DL3174.realization of the International Terrestrial Reference Frame of 2014
DL3174.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL3174.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL3174.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL3174.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL3174.currently published epoch of 2010.00.
DL3174
DL3174.Additional information on MYCS2 is available at

DL3174.The XYZ, and position/ellipsoidal ht. are equivalent.
DL3174
DL3174.The ellipsoidal height was determined by GPS observations
DL3174.and is referenced to NAD 83.
