DM7147.The coordinates were established by GPS observations
DM7147.and adjusted by the National Geodetic Survey in May 2021.
DM7147
DM7147.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DM7147.been affixed to the stable North American Tectonic Plate.
DM7147
DM7147.The coordinates are valid at the epoch date displayed above
DM7147.which is a decimal equivalence of Year/Month/Day.
DM7147
DM7147.Due to the release of the International GNSS Service (IGS) 2014
DM7147.realization of the International Terrestrial Reference Frame of 2014
DM7147.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DM7147.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DM7147.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DM7147.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DM7147.currently published epoch of 2010.00.
DM7147
DM7147.Additional information on MYCS2 is available at

DM7147.Significant digits in the geoid height do not necessarily reflect accuracy.
DM7147.GEOID18 height accuracy estimate available here.

DM7147.The XYZ, and position/ellipsoidal ht. are equivalent.
DM7147
DM7147.The ellipsoidal height was determined by GPS observations
DM7147.and is referenced to NAD 83.
