DM3531.The coordinates were established by GPS observations
DM3531.and adjusted by the National Geodetic Survey in July 2023.
DM3531
DM3531.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DM3531.been affixed to the stable North American Tectonic Plate.
DM3531
DM3531.The coordinates are valid at the epoch date displayed above
DM3531.which is a decimal equivalence of Year/Month/Day.
DM3531
DM3531.Due to the release of the International GNSS Service (IGS) 2014
DM3531.realization of the International Terrestrial Reference Frame of 2014
DM3531.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DM3531.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DM3531.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DM3531.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DM3531.currently published epoch of 2010.00.
DM3531
DM3531.Additional information on MYCS2 is available at

DM3531.Significant digits in the geoid height do not necessarily reflect accuracy.
DM3531.GEOID18 height accuracy estimate available here.

DM3531.The XYZ, and position/ellipsoidal ht. are equivalent.
DM3531
DM3531.The ellipsoidal height was determined by GPS observations
DM3531.and is referenced to NAD 83.
