DH5858.The coordinates were established by GPS observations
DH5858.and adjusted by the National Geodetic Survey in June 2019.
DH5858
DH5858.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DH5858.been affixed to the stable North American Tectonic Plate.
DH5858
DH5858.The coordinates are valid at the epoch date displayed above
DH5858.which is a decimal equivalence of Year/Month/Day.
DH5858
DH5858.Due to the release of the International GNSS Service (IGS) 2014
DH5858.realization of the International Terrestrial Reference Frame of 2014
DH5858.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DH5858.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DH5858.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DH5858.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DH5858.currently published epoch of 2010.00.
DH5858
DH5858.Additional information on MYCS2 is available at

DH5858.Significant digits in the geoid height do not necessarily reflect accuracy.
DH5858.GEOID18 height accuracy estimate available here.

DH5858.The XYZ, and position/ellipsoidal ht. are equivalent.
DH5858
DH5858.The ellipsoidal height was determined by GPS observations
DH5858.and is referenced to NAD 83.
