DM7133.The coordinates were established by GPS observations
DM7133.and adjusted by the National Geodetic Survey in June 2019.
DM7133
DM7133.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DM7133.been affixed to the stable North American Tectonic Plate.
DM7133
DM7133.The coordinates are valid at the epoch date displayed above
DM7133.which is a decimal equivalence of Year/Month/Day.
DM7133
DM7133.Due to the release of the International GNSS Service (IGS) 2014
DM7133.realization of the International Terrestrial Reference Frame of 2014
DM7133.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DM7133.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DM7133.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DM7133.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DM7133.currently published epoch of 2010.00.
DM7133
DM7133.Additional information on MYCS2 is available at

DM7133.Significant digits in the geoid height do not necessarily reflect accuracy.
DM7133.GEOID18 height accuracy estimate available here.

DM7133.The XYZ, and position/ellipsoidal ht. are equivalent.
DM7133
DM7133.The ellipsoidal height was determined by GPS observations
DM7133.and is referenced to NAD 83.
