DM4706.The coordinates were established by GPS observations
DM4706.and adjusted by the National Geodetic Survey in June 2019.
DM4706
DM4706.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DM4706.been affixed to the stable North American Tectonic Plate.
DM4706
DM4706.The coordinates are valid at the epoch date displayed above
DM4706.which is a decimal equivalence of Year/Month/Day.
DM4706
DM4706.Due to the release of the International GNSS Service (IGS) 2014
DM4706.realization of the International Terrestrial Reference Frame of 2014
DM4706.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DM4706.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DM4706.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DM4706.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DM4706.currently published epoch of 2010.00.
DM4706
DM4706.Additional information on MYCS2 is available at
DM4706.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DM4706.Significant digits in the geoid height do not necessarily reflect accuracy.
DM4706.GEOID18 height accuracy estimate available here.

DM4706.The XYZ, and position/ellipsoidal ht. are equivalent.
DM4706
DM4706.The ellipsoidal height was determined by GPS observations
DM4706.and is referenced to NAD 83.
