DH3594.The coordinates were established by GPS observations
DH3594.and adjusted by the National Geodetic Survey in June 2019.
DH3594
DH3594.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DH3594.been affixed to the stable North American Tectonic Plate.
DH3594
DH3594.The coordinates are valid at the epoch date displayed above
DH3594.which is a decimal equivalence of Year/Month/Day.
DH3594
DH3594.Due to the release of the International GNSS Service (IGS) 2014
DH3594.realization of the International Terrestrial Reference Frame of 2014
DH3594.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DH3594.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DH3594.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DH3594.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DH3594.currently published epoch of 2010.00.
DH3594
DH3594.Additional information on MYCS2 is available at
DH3594.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DH3594.Significant digits in the geoid height do not necessarily reflect accuracy.
DH3594.GEOID18 height accuracy estimate available here.

DH3594.The XYZ, and position/ellipsoidal ht. are equivalent.
DH3594
DH3594.The ellipsoidal height was determined by GPS observations
DH3594.and is referenced to NAD 83.
