DM7472.The coordinates were established by GPS observations
DM7472.and adjusted by the National Geodetic Survey in October 2020.
DM7472
DM7472.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DM7472.been affixed to the stable North American Tectonic Plate.
DM7472
DM7472.The coordinates are valid at the epoch date displayed above
DM7472.which is a decimal equivalence of Year/Month/Day.
DM7472
DM7472.Due to the release of the International GNSS Service (IGS) 2014
DM7472.realization of the International Terrestrial Reference Frame of 2014
DM7472.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DM7472.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DM7472.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DM7472.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DM7472.currently published epoch of 2010.00.
DM7472
DM7472.Additional information on MYCS2 is available at

DM7472.The XYZ, and position/ellipsoidal ht. are equivalent.
DM7472
DM7472.The ellipsoidal height was determined by GPS observations
DM7472.and is referenced to NAD 83.
