DM7496.The coordinates were established by GPS observations
DM7496.and adjusted by the National Geodetic Survey in October 2020.
DM7496
DM7496.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DM7496.been affixed to the stable North American Tectonic Plate.
DM7496
DM7496.The coordinates are valid at the epoch date displayed above
DM7496.which is a decimal equivalence of Year/Month/Day.
DM7496
DM7496.Due to the release of the International GNSS Service (IGS) 2014
DM7496.realization of the International Terrestrial Reference Frame of 2014
DM7496.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DM7496.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DM7496.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DM7496.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DM7496.currently published epoch of 2010.00.
DM7496
DM7496.Additional information on MYCS2 is available at

DM7496.The XYZ, and position/ellipsoidal ht. are equivalent.
DM7496
DM7496.The ellipsoidal height was determined by GPS observations
DM7496.and is referenced to NAD 83.
